Here m is the total mass of the reaction mixture (in g), ΔT is the maximum temperature change that occurs during the reaction (in °C), and c is the specific heat capacity of the mixture (in J/g°C). Note that since the ... Δ E = q + w. w = P Δ V and Δ V is zero when the volume is constant. So, for a constant volume, ΔE = q, and therefore, the bomb calorimeter measures the energy change of a chemical reaction. The experiment is carried out in an insulated sealed vessel called a bomb which is designed to withstand high pressures.Chemistry. Chemistry questions and answers.
