For a given chemical equation,the coefficients for each substance become the exponents for each substance in the written equilibrium expression.

Question

Quizplus · Accepted Answer

This statement is true. The equilibrium expression is written by placing the reactants in the numerator and the products in the denominator, with their coefficients used as exponents. For example, the equilibrium expression for the reaction 2A + 3B ⇌ C + D would be (C)(D)/(A)^2(B)^3.
