ChemistryNEET 2021Arrhenius equation and activation energy

Chemical Kinetics

The slope of the Arrhenius plot ( $ln k$ vs $\frac{1}{T}$ ) of a first order reaction is $- 5 \times 1 0^{3}$ K. The value of $E_{a}$ of the reaction is (given $R = 8.314 J K^{- 1} mo l^{- 1}$ ):

A. $41.5 kJ mo l^{- 1}$ ✓
B. $83.0 kJ mo l^{- 1}$
C. $166 kJ mo l^{- 1}$
D. $- 83 kJ mo l^{- 1}$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
