Vedclass · Answer

(A) The graph shows the rate of formation of the product versus time.In region-$I$,the rate increases linearly with time,which does not correspond to standard integer-order kinetics.In region-$II$,the rate approaches a constant value asymptotically.In region-$III$,the rate becomes constant,which is characteristic of a zero-order reaction (where rate is independent of concentration).Since the rate of reaction depends on the concentration of reactants,and the graph only shows rate versus time,the order of the reaction cannot be determined solely from this plot without knowing the concentration-time profile.Therefore,only statement $B$ is correct.The number of correct statements is $1$.
