Unformatted text preview: amount of heat required to raise the temperature of 1 g of substance by 1K (or 1° C) Note: 1L = 1000cm^3 Chapter 4.3 Calorimetry Calorimeter: used for measuring the amount of heat produced (liberated) or consumed (aborbed) during a chemical reaction Heat flow for the reaction system is equal in magnitude but opposite in sign to that of a calorimeter. - Calorimeters have a heat capacity, - The heat required to increase the temperature of a calorimeter by a change in temperature is given by Therefore the enthalpy difference of the reaction For processes that do not occur in solution, a bomb calorimeter is used. Chapter 4.3 Thermochemical Equations - They are already balanced equations and give an appropriate sign and value for ΔH. - The physical states (phases) of all the reactants and products must be specified s, l, g, or aq. Phase Transitions: Melting (kJ/mol) Boiling...
