On the other hand, the heat produced by a reaction measured in a bo calorimeter is not equal to ΔH, because the closed, constant-volume metal container prevents expansion work from occurring. Chemists usually perform experiments under normal atmospheric conditions, at constant external pressure with q = Δ H , which makes enthalpy the most convenient choice for determining heat.
