Question

The equilibrium constant of a reaction: A) is not related to the change in free energy of the reaction. B) is the same as the mass action ratio when the reaction is displaced from equilibrium. C) can change if the concentration of reactants and products are changed. D) is related to the change in free energy of the reaction. E) cannot be used to determine whether a reaction will proceed in the direction as written under non-standard conditions.

Answer 1

Answer:) is related to the change in free energy of the reaction--d

Step-by-step explanation:

For any reaction that is taking place at any moment the change in Gibbs Free Energy is related to the reaction quotient as

ΔG=ΔG⁰+RTlnQ

where R-Universal Gas Constant, T- Temperature in Kelvin, Q is the reaction quotient

Now when the system is in equilibrum, ΔG⁰ which is the standard Gibb's Free Energy,is then defined as

ΔG⁰=−RTlnK ,

where K is the equilibrium constant. because ΔG becomes 0 and reaction quotient Q = K

The equilibrum constant is related to the change in free energy of the reaction.

because when ΔG is negative, the value of K is high which leads to a spontaneous. reaction

when ΔG is positive, the value of K is low, which leads to a spontaneous. reaction in the opposite direction.
