Write the mass-action expression,Q_c,for the following chemical reaction.
2Cu²⁺(aq) + 4I^-(aq)
2CuI(s) + I₂(aq)

Question

Write the mass-action expression,Q_c,for the following chemical reaction. 2Cu²⁺(aq)+ 4I^-(aq) 2CuI(s)+ I₂(aq)

Quizplus · Accepted Answer

The mass-action expression is the product of the concentration of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients. The expression for the given reaction is: [CuI]2[I₂(aq)] / [Cu^2]2[(aq)]4[I^-(aq)]. Among the given choices, only option C matches this expression.
