$HI \rightleftharpoons \frac {1}{2} H_{2(g)} + \frac{1}{2} I_{2(g)}$
is $8.0$. The equilibrium constant of the reaction
$H_{2( g )} + I_{2(g)} \rightleftharpoons 2HI_{ ( g )}$ will be

(image) $\frac{{{H_2}}}{{pd - BaS{O_4}}}\,'A'$
The product $'A'$ is
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 . . . . .
