Solution: Calculate the equilibrium concentrations of NO, O 2, and NO2 in a mixture at 250 °C that results from the reaction of 0.20 M NO and 0.10 M O2. (Hint: K is large; assume the reaction goes to completion

Problem

Calculate the equilibrium concentrations of NO, O 2, and NO2 in a mixture at 250 °C that results from the reaction of 0.20 M NO and 0.10 M O2. (Hint: K is large; assume the reaction goes to completion then comes back to equilibrium.)

2NO(g) + O2(g) ⇌ 2NO2(g)             K c = 2.3 × 10 5 at 250 °C
