Question

What describes an endothermic reaction?

• A. Positive $\Delta H$
• B. Negative $\Delta H$
• C. Positive $\Delta G$
• D. Negative $\Delta G$

Answer 1

The correct option is A Positive $\Delta H$

Endothermic reactions have Positive $\Delta H$.

In endothermic reactions, energy is absorbed by a system from the surroundings. Thus in a chemical equation or reaction, products will have more energy than the reactants. Thus, $\Delta H$ will be Positive.
