For the production of NO₂, Kc = [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 Kc is ________.

Question

Quizplus · Accepted Answer

Kc is calculated using the formula: Kc = [NO2]^2 / ([NO]^2 * [O2]). Concentrations are found by dividing moles by volume. Substituting the given values, 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, Kc = [NO₂]₂/[NO]₂[O₂]
