Question

A certain equilibrium system is represented by the following chemical equation: A(g) + 2B(g) <--> 2C(g) At equilbrium, at a particular temperature. [A] = 0.88 M, [B] = 0.45 M, and [C] = 0.00022 M. Calculate the value of K for the system at this temperature.

Answer 1

K = [C]²/[A]*[B]²

K = (0.00022)²/0.88*(0.45)²

K = 2.716 x 10^-7
