Question

2A+B=C the initial amount of the reactant present in one dm3 of solution were 0.50moles of A and 0.60moles of B at equilibrium the amount were 0.20mole of A and o.45mole of B and 0.15mole of C calculate the equilibrium constant Kc

Answer 1

$Kc=\frac{[C]}{[A]^2[B]}$

$Kc=\frac{[0.15]}{[0.2]^2[0.45]}=8.33$
