Question

Consider reaction (1) shown below with it's associated equilibrium constant. What is the equilibrium constant for reaction (2)?

Report your answer to THREE significant figures.

(1) 3 A + 3 B ⇌ 3 C , K = 0.464

(2) 3 C ⇌ 3 A + 3 B , K = ??

Answer 1

Answer #1

(1). 3A + 3B 3C for this reaction K = 0.464

expression for K = [C]³/[A]³ [B]³ = 0.464. ...... (1)

(2) 3C 3A + 3B.

expression of K for this reaction is

K = [A]³ [B]³/ [C]³ which is reverse of (1)

K = 1/0.464 = 2.16

thus we calculated K of second reaction which is just reverse of (1).
