Question

A reaction occurs when solid X is placed into solution Y. As a result, the temperature of the new solution increases by 3°C. The temperature rises another 2°C when more of solid X is added to the solution. What does this indicate about the effect of adding more solid?

Answer 1

adding more of solid X will increase the heat of the solution by another few degrees

Answer 2

Answer:

The reaction is an exothermic reaction.

Explanation:

As more solid is added to the system, the temperature will increase. This will only give one possible postulate - that the reaction is an exothermic one. An exothermic reaction increases the temperature of the reaction. Thus, the total energy of the reaction will be negative.
