Unformatted text preview: Reaction releases energy o Enthalpy = delta h Enthalpy is a state function If enthalpy goes towards a reaction then goes back it should be 0 because it went through a cycle. o Hess’s Law The change in enthalpy is independent to the reaction path No matter how a reaction proceeds in how many steps the enthalpy change should be the same o Enthalpy of solution o Standard reaction enthalpy Standard conditions : t = 298 K p = 1 atm Standard State: H 2 (g) H 2 o(l) MgO(s) etc. Delta H for a reaction in which a compound is formed from its elements in their standard states-...
