Problem: Are the following processes exothermic or endothermic?a. When solid KBr is dissolved in water, the solution gets colder.

FREE Expert Solution

Recall: An endothermic reaction absorbs heat from the surroundings. The change in enthalpy for endothermic reactions is positive. Since an endothermic reaction absorbs heat from the surroundings, the temperature of the surrounding decreases.

On the other hand, an exothermic reaction releases heat to the surrounding, and the change in enthalpy is negative. Since an exothermic reaction releases heat from the surroundings, the temperature of the surrounding increases.
