053 - Enthalpy of Reaction
In this video Paul Andersen explains how the enthalpy of a reaction can be released in an exothermic or consumed in an endothermic reaction. According to Hess's law if the reaction is reversed the sign of the enthalpy of reaction is also reversed. The overall enthalpy of reaction is the sum of all the individual reactions. A couple of enthalpy of reaction problems are worked out as well.
