Q82 · CSIR NET Chemistry, June 2015

Paper: CSIR NET June 2015 · Subject: Physical Chemistry · Chapter: Chemical Kinetics · Topic: Chemical Kinetics – General · Marks: 2 · Difficulty: Medium

In a photochemical reaction, radicals formed according to the equation
$\mathrm{C_4H_{10}} + h\nu \leftrightharpoons \mathrm{2C_2H_5}$ ; $\mathrm{C_2H_5 + C_2H_5 \xrightarrow{k_2} C_2H_6 + C_2H_4}$
If I is the intensity of light absorbed, the rate of the overall reaction is proportional to-
(a)I
(b)$I_{1/2}$
(c)$I[\mathrm{C_4H_{10}}]$
(d)$I_{1/2}[\mathrm{C_4H_{10}}]_{1/2}$
