Question

Consider the following reaction:

The time taken for A to become th of its initial concentration is twice the time taken to become  of the same. Also, when the change of concentration of B is plotted against time, the resulting graph gives a straight line with a negative slope and a positive intercept on the concentration axis.

The overall order of the reaction is

Canvas Classes · Accepted Answer

From the condition on A:

For a first order reaction:  (since  halves twice → ). This is consistent with first order w.r.t. A.

From the condition on B:

A straight line with negative slope and positive intercept on the concentration axis for  vs  means , which is zero order w.r.t. B.
