Determine True and False from the given statements:
$(a)$ The rate of reaction is directly proportional to the concentration of reactant.
$(b)$ The rate of reaction is inversely proportional to the concentration of reactant.
$(c)$ The rate of reaction does not depend on the concentration of reactant.
$(a)$ The rate of reaction is directly proportional to the concentration of reactant.
$(b)$ The rate of reaction is inversely proportional to the concentration of reactant.
$(c)$ The rate of reaction does not depend on the concentration of reactant.
(A) The rate of a chemical reaction is generally expressed by the rate law: $Rate = k[Reactant]^n$,where $n$ is the order of the reaction.
$(a)$ If the reaction is of first order $(n=1)$,the rate is directly proportional to the concentration of the reactant. This statement is true for first-order reactions.
$(b)$ The rate of reaction is generally not inversely proportional to the concentration of the reactant in simple elementary steps. This statement is false.
$(c)$ For zero-order reactions $(n=0)$,the rate of reaction is independent of the concentration of the reactant $(Rate = k)$. However,in general,the rate depends on concentration. Thus,this statement is false as a general rule.
