Time : 1.30 Hours

Part - A

Generic 3 - Answer All Question

Define the Molar Heat of Fusion

What is the need for second Law of thermodynamics.

How does entropy vary when external pressure is less than internal pressure of the gaseous system?

Cyanamide (NH₂CN) is completely burnt in excess oxygen in a bomb calorimeter, ΔU was found to be -742.4 kJ mol^-1calculate the enthalpy change of the reaction at 298K. NH₂CN_(S) +\(\frac{3}{2}\)O_2(g)⟶ N_2(g)+ CO_2(g)+ H₂O(I) ΔH= ?

What happens to work when
(i) gas expands against external pressure
(ii) gas is compressed
(iii) gas expands into vacuum
(iv) an ideal gas expands reversibly and isothermally.

Bring out the differences between extensive and intensive properties.

Drive the relation between c_p and c_v for an ideal gas.

What is absolute zero temperature?

Find out the value of equilibrium constant for the following reaction at 298K; 2NH_3(g)+ CO_2(g) \(\leftrightharpoons\)

NH₂CONH_2(aq) + H₂O(I) Standard Gibbs energy change, \(\Delta G_{r}^{o}\) at the given temperature is -13.6 kJ mol^-1.
