WebLearn about exothermic and endothermic reactions and the transfer of energy with GCSE Bitesize Chemistry (AQA). Web1 mole of H—H bonds and 1 mole of Cl—Cl bonds. The amount of energy needed (from the above table) is 436 + 242 kJ = 678 kJ. When 2 moles of H—Cl bonds are formed, the amount of energy given out is 2 x 431 kJ = 862 kJ. The difference between the two amounts of energy (reactants minus products) is the overall amount of energy given out per ...
