Detailed Solution

The above statement is true.
In a chemical reaction, energy is used for breaking the bonds of the reactants, and energy is used to form new bonds. So, there are two ways to produce the energy in a reaction. They are either producing the energy or consuming the energy from the surroundings. A chemical reaction that releases energy from the products in the form of heat or light is known as an exothermic reaction.
The process of dilution of sulphuric acid with water generates heat. As it happens with the evolution of heat, it is an exothermic reaction.
The equation for this reaction is:
H2SO4 + 2H2O → 2H3O+ + SO42– + heat
