Fill in the blanks:
$(a)$ The rate of reaction ....... as the concentration of reactant decreases.
$(b)$ The rate of reaction ....... as the concentration of product increases.
$(a)$ The rate of reaction ....... as the concentration of reactant decreases.
$(b)$ The rate of reaction ....... as the concentration of product increases.
(A) The rate of reaction decreases as the concentration of reactant decreases because the frequency of effective collisions between reactant molecules reduces.
$(b)$ The rate of reaction generally decreases as the concentration of product increases,especially in reversible reactions,because the rate of the backward reaction increases,effectively reducing the net rate of the forward reaction.
$(b)$ The rate of reaction generally decreases as the concentration of product increases,especially in reversible reactions,because the rate of the backward reaction increases,effectively reducing the net rate of the forward reaction.
