According to the balanced equation, with 1 mole of Cl2, -80kJ of heat is released. So with 2 mols of Cl2, this number will double so if you do -80(2) -160kJ of heat will be produced.
Mean will give you the average in a collected data.
The rates of forward reaction and reverse reaction are constant.
