6.1.1 If the reaction produces heat (increases the temperature of the surroundings) then it’s exothermic. If it decreases the temp (i.e. absorbs heat) then it’s endothermic. Also‚ the yield of an equilibrium reaction which is exothermic will be increased if it occurs at low temps‚ and so for endothermic reactions at high temperatures. 6.1.2 Exothermic : A reaction which produces heat. Endothermic : A reaction which absorbs heat. Enthalpy of reaction : The change in internal energy (H) through
