Question

Problem 8.4 Calculating Heat Capacities Use heat capacity data to calculate the following quantities.

Liquid Toluene Correct. The heat capacity (Cp) of liquid toluene at 70.0°C: 0.1714  kJ/(mol °C)

Toluene Vapor Correct. The heat capacity at constant pressure of toluene vapor at 70.0°C: 0.1194 kJ/(mol °C)

Solid Carbon Check that you are using the right form for the heat capacity expression.   The heat capacity at constant pressure of solid carbon at 70.0°C:  _____________x 10–3 kJ/(mol K)

Change in Enthalpy for Toluene Vapor Check that you are using the right form for the heat capacity expression.   Remember that you must integrate over the temperature range. The ΔH∧(kJ/mol) of toluene vapor going from 70.0°C to 360.0°C:  ___________ kJ/mol

Change in Enthalpy for Solid Calcium Carbonate The ΔH∧(kJ/mol) of solid calcium carbonate going from 70.0°C to 360.0°C:  ___________ kJ/mol
