(c) ΔG° = RT????????K (d) ΔG = -RT????????K

Answer 1

Answer:

sorry it is tough as I'm in junior class

Answer 2

The correct relationship between free energy  and equilibrium constant K of a reaction is (a) ΔG° = - RT ln Kc

Explanation:

The Gibbs free energy is given by the formula:

ΔG = ΔG° + RT ln Q

Where,

Q = reaction quotient

At the equilibrium, we get,

ΔG = 0

ΔG° = - RT ln Q

Where, Q = Kc

∴ ΔG° = - RT ln Kc
