Thermodynamics MCQs

In the decomposition of PCl₅ represented by, PCl₅ ⇋ PCl₃ + Cl₂, decrease in the pressure of the system will __________ the degree of dissociation of PCl₅.

Normal temperature and pressure (N.T.P.) corresponds to

dW and d_q are not the exact differential, because q and W are

For a constant volume process

Which of the following equations is obtained on combining 1^st and 2^nd law of thermodynamics, for a system of constant mass?

Refrigerants commonly used for domestic refrigerators are

A reasonably general expression for vapour-liquid phase equilibrium at low to moderate pressure is Φ_i y_i P = Y_i x_i f_i° where, Φ is a vapor fugacity component, Y_i is the liquid activity co-efficient and f_i° is the fugacity of the pure component i. the K_i value (Y_i = K_i x_i) is therefore, in general a function of

The value of C_p & C_v respectively for monoatomic gases in Kcal/kg Mole . °K are
