Consider the following reaction,equilibrium concentrations,and equilibrium constant at a particular temperature.Determine the equilibrium concentration of NO₂(g) .
N₂O₄(g) ⇌ 2 NO₂(g) K_c = 0.21
[N₂O₄]_eq = 0.039 M

Question

Quizplus · Accepted Answer

The equilibrium constant expression for the reaction is:K_c = [NO₂]²/[N₂O₄]Substituting the given equilibrium concentrations into the expression, we get:0.21 = [NO₂]²/0.039Solving for [NO₂], we get:[NO₂] = 0.090 MTherefore, the equilibrium concentration of NO₂(g) is 9.0 × 10^-2 M.
