Arrhenius Collision Theory

The activation energy for the reaction $2\mathrm{HI}\left(\mathrm{g}\right)\to {\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{I}}_2\left(\mathrm{g}\right)$  is $209.5{\mathrm{kJmol}}^{-1}$ at $581\mathrm{K}$. The fraction of molecules having energy equal to or greater than activation energy is: $[\mathrm{R}=8.31{\mathrm{JK}}^{-1}{\mathrm{mol}}^{-1}]$

What is the increase in rate of the reaction, on raising the temperature by $25°\mathrm{C}$ if the temperature coefficient of a reaction is $3$?

Using the Arrhenius equation, find out the value of $\mathrm{k}$ at $\mathrm{T}\to \infty$.

If for a hypothetical reaction,${\mathrm{E}}_{\mathrm{a}}=0$ at $273 \mathrm{K}$, then find the ratio of the rate constants at $383 \mathrm{K}$.

In the Arrhenius equation, the universal gas constant can be replaced by

In the $\ln \mathrm{K }v\mathrm{s }\frac{1}{T}$ plot of a chemical process having $∆S^0>0$ and $∆H^o<0$ the slope is proportional to (where $K$ is equilibrium constant)
