Enthalpy

• q=mc^T

  q= enthalpy change

  m= mass

  c= specific heat capacity

  ^T= temp change
• Endothermic- more energy used breaking bond than making bonds
• Exothermic - more energy released making bonds than breaking bonds
• Enthalpy change of neutralisation - The enthalpy change that accompanies the reaction of an acid by a base to form one mole of H2O (l), under standard conditions and all reactants and products in their standard states
• Enthalpy change of reaction - The enthalpy change that accompanies the reaction in the molar quantities expressed in a chemical equation under standard conditions, all reactants and products being in their standard states
