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

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.
