Consider the following reaction

\(\mathrm{A}+\mathrm{B} \rightarrow \mathrm{C}\)

The time taken for A to become \(1 / 4^{\text {th }}\) of its initial concentration is twice the time taken to become \(1 / 2\) 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 ________.
