For this problem, we have to determine the direction in which the reaction will proceed.
N2O4(g) ⇌ 2 NO2(g)
Recall that the equilibrium constant is the ratio of the products and reactants. We use Kp when dealing with pressure and Kc when dealing with concentration:
Note that solid and liquid compounds are ignored in the equilibrium expression.
Since we’re given the concentration of each compound, we use Kc. The Kc expression for the reaction is:
Consider the reaction and its equilibrium constant: N2O4(g) ⇌ 2NO2(g); Kc = 5.85 x 10–3 (at some temperature)
A reaction mixture contains [NO2] = 0.0251 M and [N2O4] = 0.0331 M. Determine the direction in which the reaction will proceed.
