Q96 · CSIR NET Chemistry, December 2015
Paper: CSIR NET December 2015 · Subject: Physical Chemistry · Chapter: Chemical Kinetics · Topic: Rate Laws Order · Marks: 2 · Difficulty: Hard
The first order rate constant for a unimolecular gas phase reaction A → products that follows Lindemann mechanism is $2.0\,\mathrm{s^{-1}}$ at $p_A$ = 1 atm and $4.0\,\mathrm{s^{-1}}$ at $p_A$ = 2 atm. The rate constant for the activation step is
(a)$1.0\,\mathrm{atm^{-1}s^{-1}}$
(b)$2.0\,\mathrm{atm^{-1}s^{-1}}$
(c)$4.0\,\mathrm{atm^{-1}s^{-1}}$
(d)$8.0\,\mathrm{atm^{-1}s^{-1}}$
