Problem 70P

PROBLEM 70P

Classify each process as exothermic or endothermic and indicate the sign of ΔHrxn.

(a) ice melting

(b) a sparkler burning

(c) acetone evaporating from skin

Step-by-Step Solution:

Solution 70P

Here, we are going to classify the given processes as exothermic or endothermic.

Step 1:

Reactions in which heat is released along with the formation of products are called exothermic chemical reactions. On the other hand, reactions in which heat is absorbed are called endothermic reactions.

The value of ΔHrxn(enthalpy change, heat evolved or absorbed) is always negative for exothermic reactions and positive for endothermic reactions.
