Question

Quizplus · Accepted Answer

The equilibrium expression should include the concentrations of the species involved in the reaction, raised to their stoichiometric coefficients in the balanced chemical equation. Here, the concentrations of CuS, CuS1P1+S1S1P0, and SS1P12-S1S1P0 are raised to the power of 1, 2, and 1, respectively. Therefore, option C is the correct equilibrium expression.
