What does the equilibrium expression look like for the reaction As₂S_3(s) ⇌ 2As³⁺_(aq) + 3S^2-_(aq)?

Question

Quizplus · Accepted Answer

The equilibrium expression for a reaction is written as the product of the concentrations of the products divided by the product of the concentrations of the reactants, each raised to the power of their stoichiometric coefficients. In this case, the products are As3+ and S2-, and the reactants are As2S3. The stoichiometric coefficients are 2 for As3+ and 3 for S2-, and 1 for As2S3. Therefore, the equilibrium expression is:K = [As3+]2 [S2-]3 / [As2S3]
