| Initial $[A_2]$ | Initial $[B_2]$ | $R.O.R.\,(r)\,Ms^{-1}$ |
| $0.2$ | $0.2$ | $0.04$ |
| $0.1$ | $0.4$ | $0.04$ |
| $0.2$ | $0.4$ | $0.08$ |
Order of reaction with respect to $A_2$ and $B_2$ are respectively
If $T_1=2 T_2$ and $\left(\Delta G_2^{\Theta}-\Delta G_1^{\varphi}\right)=R T_2 \ln x$, then the value of $x$ is. . . . .
$\left[\Delta G_1^\theta\right.$ and $\Delta G_2^\theta$ are standard Gibb's free energy change for the reaction at temperatures $T_1$ and $T_2$, respectively.]
