For a reaction, given below is the graph of $ln k v s \frac{1}{T}$ . The activation energy for the reaction is equal to________ cal mol^-1 . (Nearest integer).

(Given : R = 2 cal K^-1 mol^-1 )

Answer:

Solution:

$k = A e^{- E a / RT}$

$ln k = \frac{- Ea}{RT} + ln A$

Slope $= \frac{- E a}{R} = \frac{- 20}{5}$

$E_{a} = 4 R = 8 Cal / mol$
