Which of the following statements most accurately describes the comparison between the rate constant k and the equilibrium constant k_eq?

a)
Both constants are dependent on temperature, but only K_eq is independent of concentration.
b)
The rate constant k indicates how long the reaction will take to complete, and the equilibrium constant K_eq indicates the ratio of the product concentrations to the reactant concentrations at equilibrium.
c)
A large k means that the reaction will go to equilibrium, and a large K_eqmeans that a reaction will go to completion quickly.
d)
k is formed from the concentration of the reactants raised to their stoichiometric coefficients, while K_eq is formed from the concentration of the products over the reactants each raised to its stoichiometric coefficient.

Comparison between Rate Constant k and Equilibrium Constant Keq

Dependence on Temperature:
- Both rate constant k and equilibrium constant Keq are dependent on temperature.
- However, only Keq is independent of concentration.

Interpretation of Constants:
- Rate constant k indicates how fast a reaction will proceed to completion.
- Equilibrium constant Keq indicates the ratio of product concentrations to reactant concentrations at equilibrium.

Relationship to Reaction Progress:
- A large k value does not necessarily mean that the reaction will go to equilibrium quickly.
- A large Keq value indicates that the reaction will favor the formation of products at equilibrium.

Formation of Constants:
- Rate constant k is derived from the concentrations of reactants raised to their stoichiometric coefficients.
- Equilibrium constant Keq is formed from the ratio of product concentrations to reactant concentrations, each raised to their respective stoichiometric coefficients.

Which of the following statements most accurately describes the compar...

Let’s evaluate each statement individually. A large rate constant k means that the reaction will go to equilibrium quickly, while a large equilibrium constant K_eq means that the forward reaction will go to completion, and the concentration of products will exceed that of the reactants.

K_eq is formed from the concentrations of the reactants each raised to their stoichiometric coefficients, while k is formed from the concentrations of the reactants raised to the stoichiometric coefficients only if dealing with elementary reactions. Otherwise, the order of the reaction must be determined by experimental data.

The rate constant indicates how quickly it will take to reach equilibrium, which is similar to how long the reaction will take to reach completion. The K_eq does give an indication of the relative concentrations of the reactants versus the products at equilibrium. If we are talking about ratio, then its the concentrations set to their stoichiometric coefficients.

The correct answer is that both constants are dependent on temperature. K_eq is independent of concentration. Once at equilibrium, if the concentrations of the reactants and products change, they will readjust such that the ratio equals K_eqagain. Rate is not independent of concentration; the greater the concentration, the greater the initial speed of reaction.

A cell membrane defines the limits of the cell and serves as the boundary between the cell and its surroundings. It is made of a double layer of lipids that blocks the passage of polar substances. The image below shows a typical cell membrane:One important concept related to cell membranes is membrane fluidity. Cells need to keep a certain level of flexibility in order to maintain their stability. Increasing temperature, cholesterol content, and unsaturation of the fatty acid tail of the phospholipids in the bilayer increases the membrane fluidity.Substances pass through the cell membrane by a process called “transport”. Transport can be passive if no energy is consumed or active if energy is required to transport substances across the membrane. The movement of an uncharged solute across a membrane depends on its concentration gradient, while the movement of an ion depends both on its concentration gradient and the electric potential of the membrane. Membranes are said to be polarized if the resting membrane potential is different than zero, depolarized if the membrane potential is higher than the resting membrane potential, and hyperpolarized if the membrane potential is lower than the resting membrane potential.The following table shows the characteristics of the different types of solute transport across a membrane:Q.When red blood cells are placed in a solution with a lower concentration of sodium ions, water molecules pass through the cell membrane from the outside to the inside of the cell in order to balance out the concentration of sodium ions. This is an example of what type of transport? (You may consult the attachment.)

Pyruvate generated from glycolysis can follow different catabolic paths depending on many factors. In animal tissues and under anaerobic conditions, pyruvate is reduced to lactate and NADH is oxidized to NAD+, in a reaction catalyzed by lactate dehydrogenase. During the recovery period after strenuous exercise, lactate is converted back to glucose in the liver.In an experiment, the lactate levels in blood for two athletes are measured at different times from the start of vigorous exercise. The results of the experiment are shown in the table below:Q.If an individual has a lactate dehydrogenase deficiency, what will be observed in a blood test during vigorous exercise?
