Concept introduction:
An endothermic process involves absorption of heat by the system from the surroundings, whereas an exothermic process involves liberation of heat by the system to the surroundings.
Answer to Problem 3STP
(B) Exothermic
Explanation of Solution
The given reaction is:
Here, the system is the beaker containing the above reactants and products. It is mentioned that the temperature inside the beaker drops from 24°C to 17°C. This suggests that energy is released by the system to the surroundings. Since the reaction is accompanied by a release of energy, it is termed as an exothermic reaction.
