Question

Which among the following changes are exothermic or endothermic in nature?

(b)Dilution of sulfuric acid

Answer 1

Exothermic reaction

• Exothermic reactions are reactions in which heat energy is released in the form of light or heat.

Endothermic reaction

• Endothermic reactions are reactions in which heat energy is absorbed.

Dilution of sulphuric acid

• Sulphuric acid$\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$ is one of the strongest acids.
• On dilution of sulphuric acid, it evolves huge amount of heat.
• Hence, the dilution of sulphuric acid is an exothermic reaction.
