Reaction Quotient Formula

What is reaction quotient?

Reaction quotient is the ratio product of molar concentrations of products to the product of molar concentrations of reactants with each concentration term raised to a power equal to its stoichiometric coefficient at any stage during the progress of the reaction.
The main difference between K and Q is that K describes a reaction that is at equilibrium, whereas Q describes a reaction that is not at equilibrium. To determine Q , the concentrations of the reactants and products must be known. For a given general chemical equation:
aA+bB⇌cC+dD
