What is enthalpy change? How to calculate molar enthalpy You have been asked to calculate enthalpy change for the following reaction: 2\text{Al} +\text{Fe}_2\text{0}_3\to \text{Al}_2\text{0}_3+2\text{Fe} . What is an enthalpy change in physical chemistry?
If you have a simple reaction between two molecules and know the bond enthalpies of the individual bonds, you can use the following relationship to calculate the total enthalpy change for the reaction. If it is negative, heat is released, and the reaction is exothermic; if positive, the react...
