The Heat Of Formation Concept Builder Challenges Learners To Combine Formation And Decomposition Reactions And Their Corresponding ∆H Values To Determine The Enthalpy Change For A Given Reaction.

In order to calculate the heat absorbed or heat evolved for a reaction, the theory that is used is known as hess's law of heat summation. Hf, also known as enthalpy of formation, is the enthalpy change when 1 mol of compound is formed at standard state (25°c, 1 atm) from its constituting elements in their standard state. Heat of formation is one of several important parameters used to assess the performance of energetic compounds.
