Question

What type of reaction is shown in this thermochemical equation? A + B + heat → C + D

endothermic
combination
decomposition
exothermic

Answer 1

Answer: Option (a) is the correct answer.

Step-by-step explanation:

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

For example,
`A + B + Heat \rightarrow C + D` 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,
`A + B \rightarrow C + D + Heat` is an exothermic reaction.

Therefore, we can conclude that the given thermochemical equation
`A + B + Heat \rightarrow C + D` shows endothermic type of reaction.

Answer 2

The reaction, as what is depicted in the thermonuclear equation is one of the best example of an endothermic reaction. In addition, the endothermic process revolves around the idea that the system can also absorb the energy from its surroundings, in contrast to the idea of releasing its energy to its environment.
