Reaction in which reactants give products but products do not give back reactants under the same condition is:
reversible reaction
irreversible reaction
forward reaction
backward reaction
In a reversible reaction the reaction in which the reactants change to the products is called the backward reaction and that in which the products change back to the reactants is called the forward reaction.
The reaction in which a single reactant breaks down to give simpler products is called __ reaction.
When two substances (reactants) react to give products reversibly, the reaction quotient (Q) of the reaction as the reaction proceeds
