Solution: At 25°C, the reaction 2NH3(g) ⇌ N2(g) + 3H2(g) has Kc = 2.3 x 10-9. If 0.058 mol NH3 is placed in a 2.06 L container, what will the concentrations of N2 and H2 be when equilibrium is established? Make

Problem

At 25°C, the reaction 

2NH3(g) ⇌ N2(g) + 3H2(g) 

has Kc = 2.3 x 10-9. If 0.058 mol NH3 is placed in a 2.06 L container, what will the concentrations of N2 and H2 be when equilibrium is established? 

Make simplifying assumptions in your calculations. Assume the change in NH3 concentration is insignificant if compared to initial value.
