Question

What must be true of the value of ΔG° for a reaction ifa. K > 1b. K = 1c. K < 1

Answer 1

The Product conducting automatic reaction...
constant must be K>1

Answer 2

Dear Student,

◆ Answer -

a) For K > 1, ∆G° = Negative

b) For K = 1, ∆G° = Zero

c) For K < 1, ∆G° = Positive

● Explaination -

As we ∆G° is related to equilibrium constant by relation -

∆G° = -RT.lnK

a) For K > 1

When K > 1, lnK = +ve

Hence, ∆G° = -ve

b) For K = 1

When K = 1, lnK = 0

Hence, ∆G° = O

c) For K < 1

When K < 1, lnK = -ve

Hence, ∆G° = +ve

Hope this helps you...
