Which of the following statement (s) is /are correct
For adiabatic expansion of an ideal gas 
= constant
The correct options are
A For adiabatic expansion of an ideal gas = constant
B Work done in reversible isothermal expansion is greater than that done in rev adiabatic expansion for the same increase of volume.
C Buffer capacity is maximum when concentration of weak acid and salt of its conjugate base is equal
D Equilibrium constant of an exothermic reaction decreases with increase of temperature
For adiabatic expansion of an ideal gas TVγ−1 = constant.
Work done in reversible isothermal expansion is greater than that done in rev adiabatic expansion for the same increase of volume.
Buffer capacity is maximum when concentration of weak acid and salt of its conjugate base is equal.
Equilibrium constant of an exothermic reaction decreases with increase of temperature.
Hence, all the statements are correct.
