A sample consisting of 2.0 mol CO2 occupies a fixed volume of 15.0L at 300K. When it is supplied with 2.35 kJ of energy as heat its temperature increases to 341K. Assuming the CO2 is an ideal gas, calculate work, delta U and delta H (Cp=44.22 J/Km
The final equilibrium temperature of the resulting solution is 60.8 degrees Celsius. What is the enthalpy of solution, delta H solution, of LiCl expressed in kJ per mole?
