For a reaction A(g) 
B(g) at equilibrium. The partial pressure of B is found to be one fourth of the partial pressure of A. The value of Δ G° of the reaction A 
B is
Text Solution
Verified by ExpertsThe correct answer is:
A
A (g) 
B (g) P B = 
P A P A = 4P B
K p =

= 
At equilibrium Δ G = 0.
Δ Gº = – RT λ nK P = – RTlnK P = –RT ln 
= RT ln 4
