(B) According to the rate law,the rate of a chemical reaction is generally proportional to the concentration of the reactants raised to some power.For a reaction $A \rightarrow \text{Products}$,the rate is given by $\text{rate} = k[A]^n$.As the concentration $[A]$ increases,the rate of the reaction increases for reactions with order $n > 0$.Note: For a zero-order reaction $(n = 0)$,the rate is independent of the concentration,i.e.,$\text{rate} = k[A]^0 = k$.
