Question
What is meant by reaction quotient? Give its expression.
✓

Answer

Reaction quotient: It is defined as product of molar concentration of products each raised to the power equal to their respective stoichiometric coefficients in balanced chemical equation divided by the product of molar concentration of the reactants raised to the power equal to their individual stoichiometric coffecients at any stage of reaction,
$\text{e.g.}\text{ aA}+\text{bB}\rightleftharpoons\text{cC}+\text{dD}$
$\text{Q}_{\text{c}}=\frac{[\text{C}^{\text{c}}][\text{D}]^{\text{d}}}{[\text{A}]^{\text{a}}[\text{B}]^{\text{b}}}$
