Chapter 10: Problem 12

Name two processes for which you could determine an enthalpy change.

Short Answer

Expert verified
Among many processes, enthalpy change can be determined for Combustion and Phase Transitions.

Step by step solution

01

Identifying the First Process

Combustion is a chemical process that one can determine an enthalpy change for. It is an oxidation process where a substance reacts rapidly with oxygen and gives off heat. This reaction is exothermic and the enthalpy change can be calculated knowing the initial and final states.
02

Identifying the Second Process

Phase change or phase transition is another type of process where enthalpy change can be determined. An example of this is the melting of ice into water. The energy required to accomplish this without altering the temperature is known as the enthalpy of fusion. Furthermore, the change in enthalpy for phase transitions can be calculated using the heat of transformation.
