What type of reaction is shown in this thermochemical equation? a + b + heat → c + d
endothermic
combination
decomposition
exothermic

Option (a) is the correct answer.

Explanation:

A chemical reaction in which there will be absorption of heat energy by the reactant molecules is known as endothermic reaction.

For example, is an endothermic reaction.

On the other hand, a chemical reaction in which there will be release of heat energy is known as an exothermic reaction.

For example, is an exothermic reaction.

Therefore, we can conclude that the given thermochemical equation shows endothermic type of reaction.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
