Q.
Which plot represents for an exothermic reaction?
ManipalManipal 2015
Solution:
Exothermic reactions are those in which heat/energy is released during the formation of the product.
Due to release of energy, the following equation is always followed:
$\text{Energy}_{\text{product}} < \text{Energy}_{\text{reactants}}$
In the given graphs, $H$ represents energy. According to each graph:
In graph $A: \text{Energy}_{\text{product}} < \text{Energy} _{\text {reactants }}$ is followed.
In graph $B: \text{Energy}_{\text {product }} > \text{Energy} _{\text {reactants }}$
In graph $C$ and $D : \text{Energy}_{\text{product}} = \text{Energy} _{\text {reactants }}$
