Identify the balanced chemical equation for the reaction: 2 SO3 (g) ⇌ 2 SO2 (g) + O2 (g).
Write the expression for the reaction quotient, Qc, which is based on the concentrations of the products and reactants: Qc = ([SO2]^2 * [O2]) / ([SO3]^2).
Substitute the given concentrations into the Qc expression: [SO3] = 0.500 M, [SO2] = 0.0500 M, and [O2] = 0.100 M.
Calculate the numerator of the Qc expression: ([SO2]^2 * [O2]) = (0.0500^2 * 0.100).
Calculate the denominator of the Qc expression: ([SO3]^2) = (0.500^2).
