What is an exothermic reaction? Which has greater energy in an exothermic reaction, the reactants or the products?
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+BC+D+Q(heat energy)
