What is the catalyst used in the Contact process to convert sulfur dioxide into sulfur trioxide?

Detailed Solution for Test: Contact Process & Redox Reactions - Question 1
In the Contact process, the conversion of sulfur dioxide into sulfur trioxide is facilitated by the use of a vanadium(V) oxide catalyst, denoted as V2O5. This catalyst plays a key role in promoting the desired chemical reaction efficiently and selectively, leading to the production of sulfur trioxide.

How is the required oxygen for the conversion of sulfur dioxide to sulfur trioxide sourced in the Contact process?

Detailed Solution for Test: Contact Process & Redox Reactions - Question 2
In the Contact process, the oxygen needed for the conversion of sulfur dioxide into sulfur trioxide is sourced from the air. This utilization of atmospheric oxygen is a critical aspect of the process, as it provides the necessary reactant for the chemical reaction to proceed efficiently in the presence of the catalyst.

What effect does an increase in temperature have on the equilibrium in the Contact process?

Detailed Solution for Test: Contact Process & Redox Reactions - Question 3
In the Contact process, an increase in temperature causes the equilibrium to shift towards the left. This shift favors the formation of reactants rather than products. It is important to note that this process is exothermic, meaning it releases heat when it occurs. While a higher temperature can speed up the reaction rate, it ultimately leads to a lower yield of sulfur trioxide due to the shift in equilibrium towards the left.

Why is operating at slightly above atmospheric pressure preferred in the Contact process?
Detailed Solution for Test: Contact Process & Redox Reactions - Question 4
Operating at slightly above atmospheric pressure in the Contact process is preferred because it favors the production of sulfur trioxide. At higher pressures, the equilibrium heavily favors the formation of sulfur trioxide, with the mixture containing approximately 96% sulfur trioxide. This is advantageous for maximizing the yield of the desired product in the Contact process.

What safety risks are associated with high pressures in the Contact process?
Detailed Solution for Test: Contact Process & Redox Reactions - Question 5
High pressures in the Contact process can pose serious safety risks, including an increased risk of explosion. Operating at high pressures requires specialized equipment to handle the conditions safely. The potential for explosions under high pressure underscores the importance of carefully managing and controlling pressure levels in industrial processes like the Contact process.

How does the equilibrium position change with an increase in pressure in the Contact process?
Detailed Solution for Test: Contact Process & Redox Reactions - Question 6
When pressure increases in the Contact process, the equilibrium shifts towards the right. This shift favors the formation of a smaller number of gaseous molecules, particularly sulfur trioxide. At higher pressures, the equilibrium position heavily favors the production of sulfur trioxide, leading to a higher concentration of the desired product in the mixture.
Test: Contact Process & Redox Reactions - Question 7
Save
In a redox reaction, what specifically occurs during the process of oxidation?
Detailed Solution for Test: Contact Process & Redox Reactions - Question 7
In a redox reaction, oxidation involves the addition of oxygen to an element or compound. This process results in the element or compound losing electrons, increasing its oxidation state. This is a fundamental concept in redox reactions where the substance being oxidized experiences this gain of oxygen.

How are transition elements unique in terms of forming ions and naming conventions?
Detailed Solution for Test: Contact Process & Redox Reactions - Question 8
Transition elements possess the ability to form ions with varying charges, resulting in different bonding patterns. This characteristic leads to the use of Roman numerals in nomenclature to indicate the charge on the ion following the element's name. This naming convention helps distinguish between ions with different oxidation states, such as iron(II) and iron(III) ions.

What is the significance of the oxidation numbers in naming compounds of transition elements?
Detailed Solution for Test: Contact Process & Redox Reactions - Question 9
Oxidation numbers play a crucial role in naming compounds of transition elements as they help specify the oxidation state of the transition metal within the compound. By indicating the charge on the metal ion, oxidation numbers aid in correctly naming and representing compounds, such as iron(II) oxide and iron(III) oxide, based on the oxidation state of the transition element.
Test: Contact Process & Redox Reactions - Question 10

What role does carbon play in the given chemical equation involving zinc oxide and carbon monoxide?
Detailed Solution for Test: Contact Process & Redox Reactions - Question 10
In the chemical reaction provided, carbon undergoes reduction as it gains oxygen from zinc oxide, leading to the formation of carbon monoxide. This reduction process involves the carbon atom increasing its oxidation state by accepting oxygen, highlighting its role as the reducing agent in the reaction.
