Answer 2

Step-by-step explanation:

A chemical reaction in which heat energy is absorbed by the reactant molecules is known as an endothermic reaction.

For example,
`A + B + Heat \rightarrow AB`

The value of
`\Delta H` = +ve for endothermic reaction.

Whereas a chemical reaction in which heat energy is released by the reactant molecules is known as an exothermic reaction.

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

The value of
`\Delta H` = -ve for exothermic reaction.

Also, the given reaction,
`2C_(2)H_(4)O(g) + 5O_(2)(g) \rightarrow 4CO_(2)(g) + 4H2O(l)`
`\Delta H = -2385 kJ`

It is also an exothermic reaction because heat is releasing as value of
`\Delta H` is negative.

Thus, we can conclude that the given reaction is exothermic in nature.
