What is the value of the equilibrium constant at 500 °C for the formation of NH _{3} according to the following equation?

N_{2}(g) + 3H_{2}(g) ⇌ 2NH_{3}(g)

An equilibrium mixture of NH_{3}(g), H_{2}(g), and N_{2}(g) at 500 °C was found to contain 1.35 M H _{2}, 1.15 M N_{2}, and 4.12 × 10^{−1} M NH_{3}.

Watch Solution

Convert the values of K_{c} to values of K_{P} or the values of K_{P} to values of K_{c}.

(a) Cl_{2}(g) + Br_{2}(g) ⇌ 2BrCl(g) K _{c} = 4.7 × 10^{−2} at 25 °C
