Equilibrium Question 552

Question: At a given temperature, the equilibrium constant for reaction PCl5(g)PCl3(g)+Cl2(g) is 2.4×103 . At the same temperature, the equilibrium constant for reaction PCl3(g)+Cl2(g)PCl5(g) is [KCET 1992]

Options:

A) 2.4×103

B) 2.4×103

C) 4.2×102

D) 4.8×102

Show Answer

Answer:

Correct Answer: C

Solution:

Reaction is reversed. Hence K=1(2.4×103)=4.2×102
