For a reaction obeying the Arrhenius equation, a plot of ln k against (1/RT) is a straight line with slope equal to -y. What is the activation energy of the reaction?
- y unit
- -y unit
- yR unit
- y/R unit
Correct answer: y unit
Solution
Since ln k = ln A - Ea(1/RT), plotting ln k vs (1/RT) gives slope -Ea; given slope = -y, so Ea = y.
