For an endothermic reaction, where $\mathrm{\Delta H}$ represent the enthalpy of reaction in $\mathrm{kJ} {\mathrm{mol}}^{-1}$, the minimum value for energy of activation (for forward reaction) will be

$\frac{{\mathrm{k}}_{35°}}{{\mathrm{k}}_{34°}}>1,$ this means that:

What is the normality of $2{\mathrm{MH}}_3{\mathrm{PO}}_2$ solution?

In the formation of sulphur trioxide by the contact process $2{\mathrm{SO}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)2{\mathrm{SO}}_3\left(\mathrm{g}\right)$. The rate of reaction is expressed as $-\frac{\mathrm{d}\left({\mathrm{O}}_2\right)}{\mathrm{dt}}=2.5\times {10}^{-4}{\mathrm{molL}}^{-1}{\sec }^{-1}$. The rate of disappearance of $\left({\mathrm{SO}}_2\right)$ will be:-
