Test: Electrolysis - Question 3

Which of the following metals is not included in the electrochemical series?

Detailed Solution for Test: Electrolysis - Question 3

The electrochemical series lists metals in increasing order of their standard reduction electrode potentials. It helps predict the direction of redox reactions. Potassium is not included in the series: K < Ca < Na < Mg < Al < Zn < Cr < Fe < Ni < H < Cu < Hg < Ag < Pd < Pt < Au.

Test: Electrolysis - Question 4

What is a primary characteristic of a good battery?

Detailed Solution for Test: Electrolysis - Question 4

A primary characteristic of a good battery is being lightweight and compact. This feature is essential for the portability and usability of devices powered by batteries. Lighter and more compact batteries are preferred in various applications to enhance convenience and efficiency.

Test: Electrolysis - Question 5

How do fuel cells differ from traditional combustion engines in terms of energy conversion?

Detailed Solution for Test: Electrolysis - Question 5

Fuel cells directly convert the energy from fuel combustion into electrical energy, making them more efficient than traditional combustion engines. This process is cleaner and produces only water as a byproduct, offering a more environmentally friendly energy conversion method.

Test: Electrolysis - Question 6

What is the primary function of Microbial Fuel Cells (MFCs) of water treatment?

Detailed Solution for Test: Electrolysis - Question 6

Microbial Fuel Cells (MFCs) are bioelectrochemical devices used to harvest energy through anaerobic digestion, specifically for collecting bioenergy from wastewater. This process helps in water treatment by utilizing microbial activity to generate electricity.

Test: Electrolysis - Question 7

What is the primary chemical process involved in the formation of rust on iron surfaces?

Detailed Solution for Test: Electrolysis - Question 7

The formation of rust on iron surfaces primarily involves the process of oxidation, where the iron metal loses electrons to oxygen in the presence of moisture, leading to the characteristic reddish-brown appearance of hydrated iron oxide. This chemical reaction accelerates the deterioration of iron objects over time.

Test: Electrolysis - Question 8

What is the primary function of a catalyst in a chemical reaction?

Detailed Solution for Test: Electrolysis - Question 8

A catalyst functions by lowering the activation energy required for a reaction to occur, thereby speeding up the rate of the reaction. By providing an alternative reaction pathway with a lower activation energy, a catalyst facilitates the conversion of reactants to products without being consumed in the process.

Test: Electrolysis - Question 9

In enzyme catalysis, what factor significantly influences the rate of enzymatic reactions?

Detailed Solution for Test: Electrolysis - Question 9

The rate of enzymatic reactions is greatly affected by temperature. Enzymes are sensitive to temperature changes, with an optimal range usually between 25-37°C. Temperature influences the activity of enzymes, impacting the rate at which they catalyze reactions.

Test: Electrolysis - Question 10

Why are solid catalysts typically more effective when they are finely divided?

Detailed Solution for Test: Electrolysis - Question 10

Solid catalysts are more effective when finely divided because it increases their surface area available for interaction with reactant molecules. This heightened surface area enhances the catalyst's reactivity and the efficiency of the catalytic process, leading to a more rapid conversion of reactants into products.

Test: Electrolysis - Question 11

What is the primary purpose of electrolysis of an electrolytic cell?

Detailed Solution for Test: Electrolysis - Question 11

In the process of electrolysis within an electrolytic cell, the primary purpose is to induce a chemical reaction through the application of an external voltage source. This reaction leads to the decomposition of compounds and the deposition of materials at the electrodes. Electrolysis is a crucial technique used in various industries for metal purification, extraction, and organic compound synthesis.

Test: Electrolysis - Question 12

What is a defining characteristic of primary batteries?

Detailed Solution for Test: Electrolysis - Question 12

Primary batteries are characterized by the fact that the chemical reaction within them occurs only once, leading to their eventual depletion. This distinguishes them from secondary batteries which can be recharged multiple times. The limited reaction in primary batteries makes them suitable for devices where longevity is not a primary concern, and they are commonly found in items like transistors and clocks.

Test: Electrolysis - Question 13

What is the primary function of a catalyst in a chemical reaction?

Detailed Solution for Test: Electrolysis - Question 13

The primary function of a catalyst in a chemical reaction is to alter the rate of the reaction without being consumed in the process. By lowering the activation energy required for the reaction to proceed, a catalyst facilitates the reaction without changing the equilibrium state or initiating the reaction itself. This property makes catalysts crucial in speeding up various chemical processes in industries and laboratories.

Test: Electrolysis - Question 14

What distinguishes primary batteries from secondary batteries in terms of their functionality?

Detailed Solution for Test: Electrolysis - Question 14

Primary batteries are designed for single use and are disposable, meaning they cannot be recharged. On the other hand, secondary batteries are rechargeable, allowing them to be reused after being discharged. This difference in functionality is important in choosing the right type of battery for various applications.

Test: Electrolysis - Question 15

How can the process of corrosion be effectively prevented for metals like iron?

Detailed Solution for Test: Electrolysis - Question 15

Corrosion of metals like iron can be effectively prevented by applying a protective layer of zinc coating, also known as galvanizing. This process forms a barrier that shields the metal from direct contact with corrosive agents, thereby inhibiting the oxidation reaction that leads to rust formation.
