For the production of NO₂,K_c = [NO₂]²/[NO]²[O₂].At equilibrium in a 2.50 L container,there are 3.00 mol NO,4.00 mol O₂ and 22.0 mol NO₂.The value of K_c is ________.

Question

Quizplus · Accepted Answer

The equilibrium concentrations are [NO] = 3.00 mol / 2.50 L, [O2] = 4.00 mol / 2.50 L, and [NO2] = 22.0 mol / 2.50 L. Plug these into the Kc expression to find Kc = (22.0/2.50)^2 / ((3.00/2.50)^2 * (4.00/2.50)) = 33.6.

For the Production of NO2,Kc = [NO2]2/[NO]2[O2]

For the Production of NO₂,K_c = [NO₂]²/[NO]²[O₂]
