Question

The overall change in enthalpy of a reaction depends only on

Answer 1

The choices can be found elsewhere and as follows:

A. the reactants and the products.
B. the path that is taken from the reactants to the products.
C. the reactants and the catalysts only.
D. the reactants, the products, and the catalysts.

I believe the correct answer is option A. The overall change in enthalpy of a reaction depends only on the reactants and the products. Hope this answers the question. Have a nice day.

Answer 2

Answer;

A. the reactants and the products.

Step-by-step explanation;

• The enthalpy of a reaction is the heat released or absorbed by a reaction at constant pressure.
• Enthalpy is important as it tells us the amount of heat energy present in a system. In chemical reactions it tells us the amount of heat energy lost or gained.
• Changes in enthalpy are determined as the reactants are converted into products. Therefore, enthalpy depends on the reactants and the products. In other words it depends on the heat of reactants and that of products.
