What is the mass-action expression, Q_p, for the following reaction? SbF₅(g) + 4Cl₂(g) SbCl₃(g) + 5ClF(g) E) None of the above is the correct mass-action expression.

Question

Quizplus · Accepted Answer

The mass-action expression is formed by taking the product of the concentrations of the products raised to their coefficients and dividing it by the product of the concentrations of the reactants raised to their coefficients. Therefore, for this reaction, the mass-action expression will be:

[SbCl13][ClF]^5 / [SbF15][Cl12]^4

The correct choice is B, which matches this expression.
