Question

which quantity out of ∆rG and ∆rG° will be zero at equilibrium??​

Answer 1

Answer:

The

criterion for equilibrium A+B⇐C+D; is

Δ

r

G=0

Gibbs energy

for a reaction in which all reactants and products are in standard state, Δ

r

G

⊖

is related to the equilibrium constant of the reaction as

follows:

Answer 2

Answer:

Gibbs energy for a reaction in which all reactants and products are in standard state. ΔrG° is related to the equilibrium constant of the reaction as follows

ΔrG = ArG° + RT In K

At equilibrium, 0 = ΔrG° + RT In A– ({ΔrG = 0) or ΔrG° =-RT lnK

ΔrG° = 0 when K= 1

For all other values of K, ArG° will be non-zero.
