Question

A chemical reaction has a H of -2764 kj. This indicates that the chemical reaction that took place was:

A. Endothermic
B. Exothermic
C. Neutralization
D. Solvation

Answer 1

It's Exothermic

Step-by-step explanation:

Endothermic is absorbing, while exothermic is releasing.

If it was H of 2764 kj the answer would be Endothermic.

Answer 2

This is an exothermic reaction in which the energy is released to the surroundings, so the enthalpy change ΔH
ΔH = Hproducts - Hreactants
is negative.

An endothermic reaction has a positive enthalpy change. Neutralization reactions occuring between an acid and a base are generally exothermic while solvation or dissolution can be endothermic or exothermic.
