Question

For certain chemical reaction , 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) Overall 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.

From the graph of rate of formation of Y vs time:

- Region I: Rate increases linearly with time (or is constant) — this region shows the rate is constant, characteristic of zero order w.r.t. time, but the rate of formation increases as concentration of X decreases... Actually, if rate is constant in region I, it is zero order.

- Region II: Rate changes gradually — this is a transition region where the order is fractional (between 0 and 1), i.e., in the range 0.1 to 0.9.

- Region III: Rate dec
