Question

A system at equilibrium is represented by the following chemical equation: 2A(g) +B(g) <--> 4C(g) At equilbrium, this system has a [A] = 0.45 M and [C] = 0.75 M and K = 0.213, what is the [B]?

Answer 1

K = [C]⁴ / [A]²[B]

[B] = [C]⁴ / [A]²K = 0.3164 / (0.2025 x 0.213) = 7.34M

Answer: 7.34M
