For the general equation of the nature
xP + yQ ⇌ mR + nS, the expression for the equilibrium constant is

A.

k[P] $^x$ [Q] $^y$

B.

$\frac{m[R][S]}{x[P]y[Q]}$

C.

$\frac{[P]^x[Q]^y}{[R]^m[S]^n}$

D.

$\frac{[R]^m[S]^n}{[P]^x[Q]^y}$

View answer & explanation

Correct answer is D

Given:
xP + yQ ⇌ mR + nS
Let us assume they are all in aqueous solution

k = $\frac{[R]^m[S]^n}{[P]^x[Q]^y}$
