Current Question (ID: 18296)

Question:

$\text{The correct representation of an exothermic reaction is:}$

Options:

1. $\text{Graph showing reactants with higher energy than products, indicating an exothermic reaction.}$
2. $\text{Graph showing products with higher energy than reactants, indicating an endothermic reaction.}$
3. $\text{Graph showing a different energy profile not matching exothermic reaction.}$
4. $\text{Both 1 and 2}$

Solution:

$\text{The chemical reaction in which energy is evolved during the reaction is exothermic known as exothermic reaction i.e. activation energy of the product is greater than the activation energy of reactants.}$ $\text{Here, only (1) denotes the correct picture of the exothermic reaction.}$
