Summary - Enthapy changes
This chapter will teach you how to: -understand the term enthalpy change and apply it to exothermic and endothermic chemical reaction. -construct a reaction pathway in terms of enthalpy changes and activation energy. -define the term standard conditions. - know about the variety of enthalpy changes such enthalpy change of formation, combustion, reaction and neutralisation. -use bon energies to calculate enthalpy change of reaction.
