Questions + Answers key
Take MCQ Chemistry Test1.
Give expressions for the entropy change a-phase change.
2.
Describe the application of heat of combustion.
3.
Explain why Cp is always greater than Cv?
4.
Define molar heat capacity at constant volume and molar heat capacity at constant pressure.
5.
Explain Zeroth law of thermodynamics.
1.
\(\Delta S=\frac { { q }_{ rev } }{ T } =\frac { \Delta { H }_{ rev } }{ T } \)
Where \(\Delta\)Hrev is the enthalpy change at Temperature (T)
2.
(i) The heat of formation of compounds can be calculated from heat of combustion values.
(ii) The calorific value of food and fuels can be calculated from heat of combustion.
3.
At constant pressure processes, a system has to do work against the surroundings. Hence, the system would require more heat to effect a given temperature rise than at constant volume, so Cp is always greater than Cv.
4.
(i) The heat capacity at constant volume (Cv) is defined as the rate of change of internal energy with respect to temperature at constant volume.
\({ C }_{ v }={ \left( \frac { \partial H }{ \partial T } \right) }_{ v }\)
(ii) The molar heat capacity at constant pressure (Cp ) can be defined as the rate of change of enthalpy with respect to temperature at constant pressure.
\({ C }_{ P }={ \left( \frac { \partial H }{ \partial T } \right) }_{ P }\)
5.
According to this law, if systems Band C separately are in thermal equilibrium with another system A, then systems Band C will also be in thermal equilibrium with each other. This is also the principle by which thermometers are used.
