What is an exothermic reaction? Which has greater energy in an exothermic reaction, the reactants or the products?

Step-by-Step Solution:

Solution 22Q

Step 1:

The chemical reactions which proceed with the evolution of heat energy are called exothermic reactions.The heat energy produced during the reaction is indicated by writing +Q (or more precisely by giving the actual numerical value )on the product side.

Exothermic reaction can be represented as given below

A+B $\rightarrow{}$ C+D+Q(heat energy)
