Changes of Energy - 1

Changes of Energy - 1. Change of energy depends only on initial and final states In general: Constant volume: Pressure-volume work only No electrical work, etc. From definition of heat capacity:. Energy vs. Enthalpy. Define a new state function, enthalpy: Why?

Thermochemistry

Thermochemistry. Thermochemistry is the study of heat changes that occur during chemical reactions. Heat (q) - energy that is transferred from one object to another because of a temperature difference between them. Heat always flows from a warmer object to a cooler object.

Enthalpy

Enthalpy. In an exothermic reaction: e nergy flows out of the system . The flow of heat is negative (-) for the system. In an endothermic reaction: e nergy flows into the system . The flow of heat is positive (+) for the system. Enthalpy.
