Kc is defined as concentration of product by concentration of reactant with each concentration term raised to power that is equal to its stoichiometric coefficient in balanced equation
So,
Kc = [C]^2 / [A]^2[B]
= (0.071)^2 / (0.138^2 * 0.154)
= 1.72
T = 308 K
use:
ΔGo = -R*T*ln Kc
= - 8.314*308* ln(1.72)
= -1389 J
= -1.39 KJ
Answer: -1.39 KJ
