13.4 Exercise 3

Avg difficulty 2.5

What is the value of the equilibrium constant at 500 °C for the formation of NH3 according to the following equation?

N2(g)+3H2(g)⇌2NH3(g)\text{N}_{2} \left(g\right) + 3 \text{H}_{2} \left(g\right) \rightleftharpoons 2 \text{NH}_{3} \left(g\right)

An equilibrium mixture of NH3(g), H2(g), and N2(g) at 500 °C was found to contain 1.35 M H2, 1.15 M N2, and 4.12 ×\times 10−1 M NH3.
