Surface Chemistry

For the adsorption of hydrogen on platinum, the activation energy is \(30 ~\mathrm{k} ~\mathrm{J} \mathrm{mol}^{-1}\) and for the adsorption of hydrogen on nickel, the activation energy is \(41.4 ~\mathrm{k} ~\mathrm{J} \mathrm{mol}^{-1}\). The logarithm of the ratio of the rates of chemisorption on equal areas of the metals at \(300 \mathrm{~K}\) is __________ (Nearest integer)

Given: \(\ln 10=2.3\)

\(\mathrm{R}=8.3 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}\)
