A. The formula for Keq is:

Keq = concentration of product [B] / concentration of reactant [A]

where

A = 3 B

 

Therefore Keq is:

Keq = [B] / [3 B]

Keq = 0.33

 

B. The formula for ΔG° is:

ΔG° = - R T ln(Keq)

Since Keq is 0.33 and ln Keq = - 1.1, therefore:

ΔG° = - R T (- 1.1)

ΔG° = +

Therefore ΔG° is positive
