List of top Chemistry Questions on Thermodynamics asked in CUET (PG)

An ideal gas expands isothermally from an initial volume \( V_i \) and pressure \( P_i \) to a final volume \( V_f \). If the same gas is allowed to expand adiabatically from the same initial volume and pressure to the final volume \( V_f \), then
The chemical potential of one component of a mixture cannot change independently of the chemical potentials of the other components. This statement relates to:

A. \( \Delta H = -ve, \Delta S = -ve, \Delta G = -ve \)I. Reaction will be non-spontaneous at high temperature
B. \( \Delta H = -ve, \Delta S = -ve, \Delta G = +ve \)II. Reaction will be non-spontaneous at low temperature
C. \( \Delta H = +ve, \Delta S = +ve, \Delta G = +ve \)III. Reaction will be spontaneous at low temperature
D. \( \Delta H = +ve, \Delta S = +ve, \Delta G = -ve \)IV. Reaction will be spontaneous at high temperature
