(1/2)A(g) + (1/3)B(g) xrightleftharpoonsT(K) (2/3)C(g) Equilibrium constant, Kc=( text Rate product / text Rate of reactant ) Kc=([C]2 / 3/[A]1 / 2[B]1 / 3)

Q. What is the equation for the equilibrium constant $(K_{c})$ for the following reaction? $\frac{1}{2} A (g) + \frac{1}{3} B (g) T (K) \frac{2}{3} C (g)$

$K_{c} = \frac{[ A ] ^{1/2} [ B ] ^{1/3}}{[ C ] ^{3/2}}$

$K_{c} = \frac{[ C ] ^{3/2}}{[ A ] ^{2} [ B ] ^{3}}$

$K_{c} = \frac{[ C ] ^{2/3}}{[ A ] ^{1/2} [ B ] ^{1/3}}$

$K_{c} = \frac{[ C ] ^{2/3}}{[ A ] ^{1/2} + [ B ] ^{1/3}}$

$\frac{1}{2} A (g) + \frac{1}{3} B (g) T (K) \frac{2}{3} C (g)$
Equilibrium constant, $K_{c} = \frac{Rate product}{Rate of reactant}$
$K_{c} = \frac{[ C ] ^{2/3}}{[ A ] ^{1/2} [ B ] ^{1/3}}$
