Enthalpy of Reaction

The video covers the enthalpy of reaction, explaining how energy is absorbed or released during chemical reactions. It discusses Alfred Nobel's use of nitroglycerin and the invention of dynamite. The video explains bond energy, endothermic and exothermic reactions, and introduces Hess's Law and enthalpy diagrams. It also covers the Born-Haber cycle and demonstrates problem-solving using Hess's Law to calculate enthalpy changes.

What happens to the change in enthalpy when a reaction is reversed?

Describe the process of measuring enthalpy changes using a calorimeter.

In the context of the Born-Haber cycle, how do smaller reactions contribute to the overall enthalpy change?
