The reaction P4 + 5O2 → P4O10 + 712 kcal is exothermic. True False
Nitella [24]

Answer: The correct answer is true.

Explanation:

There are two types of reactions based on the heat absorbed or released:

1. Exothermic reactions: In these reactions, heat is released. The energy of the products is less than the energy of the reactants. The \Delta H for these reactions is negative.

2. Endothermic reactions: In these reactions, heat is absorbed by the reactants. The energy of the products is more than the energy of the reactants. The \Delta H for these reactions is positive.

In the given equation:

P_4+5O_2\rightarrow P_4O_{10}+712kCal

The energy is written on the product side, which means that the heat is released in the reaction. Hence, the given equation is a exothermic reaction.

Therefore, the given statement is true.
