Consider the following reaction: NO(g) + SO₃(g) ⇌ NO₂(g) + SO₂(g)
A reaction mixture initially contains 1.24 bar NO and 0.92 bar SO₃. Determine the equilibrium pressure of NO₂ if K_p for the reaction at this temperature is 0.0118.

Quizplus · Accepted Answer

To find the equilibrium pressure of NO₂, we set up the expression for Kp: Kp = (P_NO2 * P_SO2) / (P_NO * P_SO3). Let x be the change in pressure at equilibrium for NO₂ and SO₂. Then, P_NO2 = P_SO2 = x, P_NO = 1.24 - x, and P_SO3 = 0.92 - x. Substituting these into the Kp expression and solving for x gives x ≈ 0.10 bar.
