Interpretation Introduction

Interpretation:

The faster reaction among the reaction with activation energy ${\text{E}}_{\text{act}}\text{=}\text{+}\text{5kcal/mol}\left(\text{+20}\text{.9}\text{kJ/mol}\right)$ and the reaction with activation energy ${\text{E}}_{\text{act}}\text{=}\text{+10kcal/mol}\left(\text{+41}\text{.8}\text{kJ/mol}\right)$ is to be identified and explained briefly.

Concept Introduction:

• Activation energy: It is defined as the minimum energy required by the reacting species in order to undergo chemical reaction.
• The reaction having low activation energy has high rate of reaction whereas the reaction having high activation energy has low rate of reaction since the minimum energy for the collision is small resulting in less number of collisions.
• Rate of reaction: The speed in which a reaction takes place.
