Chemical Energetics - Construction of cycle

The drawing of the energy cycle is essential in trying to calculate the enthalpy change of a reaction. This value is an unknown, thus in order to enable you to calculate it, you will be given at least two know enthalpy values and their respective thermochemical chemical equation (note that such equations, state symbols are essential).

In this entry, there are two videos available. The first video provides a simplified guide to the rules of constructing an energy cycle. While the second video shows how these rules are applied to construct the energy cycle.

The first video: A simplified guide to drawing an energy cycle.

The second video: Application of rules to an actual example.
