Question

Define reaction quotient (Q).

Answer 1

Reaction quotient (Q) is defined as the ratio of the product of initial concentration of the reactants under non-equilibrium condition.
$aA+bB\rightleftharpoons 1L+mM$
$Q=\frac{{\left[L\right]}^1}{{\left[A\right]}^a}\frac{{\left[M\right]}^m}{{\left[B\right]}^b}$
