For the adsorption of hydrogen on platinum, the activation energy is $\displaystyle 30 \mathrm{k} \mathrm{J} \mathrm{mol}^{-1}$ and for the adsorption of hydrogen on nickel, the activation energy is $\displaystyle 41.4 \mathrm{~kJ} \mathrm{~mol}^{-1}$. The logarithm of the ratio of the rates of chemisorption on equal areas of the metals at $\displaystyle 300$ K is $\displaystyle \_\_\_\_$ (Nearest integer) Given: $\displaystyle \ln 10=2.3$ $$\mathrm{R}=8.3 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1} $$
