Question

Which of the following statements correctly describe the two reactions outlined below? Select all that apply

Reaction 1: A -> B deltaH = +50 kJ
Reaction 2: C -> D deltaH = -100 kJ

Answer 1

Reaction 1 and Reaction 2 are both exothermic.

Step-by-step explanation:

The two reactions outlined below are exothermic. Reaction 1 (A -> B) has a deltaH of +50 kJ, which indicates that it releases heat as it proceeds. Reaction 2 (C -> D) has a deltaH of -100 kJ, indicating an even larger release of heat.
