What is the equilibrium constant for the reaction A + B ⇌ 2C if the equilibrium concentrations are: [A] 0.419 M, [B] 0.329 M, [C] 97.2 mM?
A) 0.123 M
B) 0.685
C) 1.47
D) 68537
E) 0.0685

Quizplus · Accepted Answer

The equilibrium constant (Kc) is calculated using the equilibrium concentrations of the reactants and products:Kc = [C]^2 / [A] [B]Substituting the given equilibrium concentrations:Kc = (97.2 mM)^2 / (0.419 M) (0.329 M)Converting mM to M:Kc = (97.2 x 10^-3 M)^2 / (0.419 M) (0.329 M)Kc = 0.0685 M
