4 Decomposition of HI on the surface of Gold
Explanation:
(d) Units of rate constant of a zero order reaction are \(\mathrm{mol} \mathrm{L}^{-1} \quad \mathrm{~s}^{-1}\) as rate \(=\mathrm{k}[\mathrm{A}]^{\mathrm{n}}\) \(=\mathrm{k}[\mathrm{A}]^{\circ}=\mathrm{k}\).
Decomposition of HI on gold surface is independent of the concentration of HI so it is a zero order reaction.

For a reaction, the value of rate constant at 300 K is \(6.0 \times 10^5 \mathrm{~s}^{-1}\). The value of Arrhenius factor A at infinitely high temperature is:

The rate constants \(\mathrm{k}_1\) and \(\mathrm{k}_2\) for two different reactions are \(10^{16} \times \mathrm{e}^{-2000 / \mathrm{T}}\) and \(10^{15} \times \mathrm{e}^{-1000 / \mathrm{T}}\) respectively. The temperature at which \(k_1=k_2\) is:
