The time taken for $A$ to become $1 / 4^{\text {th }}$ of its inital 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 . . . . .
(At. No. $Ti = 22, Cr = 24, Co = 27, Zn = 30$)
$A\xrightarrow{{{K_1}}}B$, activation energy $= Ea_1$
$A\xrightarrow{{{K_2}}}C$, activation energy $= Ea_2$
if $E{a_1} = \frac{{E{a_2}}}{3}$ then the relation between $K_1$ and $K_2$ is
