Heat Flow – Constant Volume Under constant volume conditions: E = q v + w = q v -P ex ( V) E = q v For reactions which do not change significantly in volume (e.g. no change in moles of gas) q p and q v will be similar so: H E If there is a change in moles of gas: H = E + P V = ∆ Ε + nRT

Calorimetry Calorimetry is the measurement of heats of reactions from which E and H values are established A calorimeter is a device for which the heat capacity, C, is known Measurement of a temperature change allows the determination of the amount of heat generated (exothermic) or absorbed (endothermic) by the reaction
