Question

A reaction occurs in a calorimeter, resulting in the starting and final temperatures shown below. What can you say about the reaction and the enthalpy change (ΔH) during the reaction? Starting: 21.0 C Final: 38.8 C

Answer 1

The reaction is exothermic the ΔH decreases

Step-by-step explanation:

The temperature inside the calorimeter rises therefore the reaction has put heat out meaning it is an exothermic reactionand the ΔH decreases
