Question

For certain chemical reaction X 🡢 Y, the rate of formation of product is plotted against the time as shown in the figure. The number of correct statement/s from the following is______.
(A) Over all order of this reaction is one
(B) Order of this reaction can't be determined
(C) In region I and III, the reaction is of first and zero order respectively
(D) In region-II, the reaction is of first order
(E) In region-II, the order of reaction is in the range of 0.1 to 0.9.

Answer 1

The correct answer is 2
Ether the order w.r.t. reaction is negative in region I and II or the order of the reaction depends only on the concentration of product. So by that reasoning if order of the reaction depends only on the concentration of product then statement C and E are correct.
