The pressure-volume of various thermodynamic process is shown in graphs:

Work is the mole of transference of energy. It has been observed that reversible work done by the system is the maximum obtainable work.
`w_(rev) gt w_(irr)`
The works of isothermal and adiabatic processes are different from each other.
`w_("isothermal reversible") = 2.303 nRT log_(10) ((V_(2))/(V_(1)))`
`= 2.303 nRT log_(10)((P_(2))/(P_(1)))`
`w_("adiabatic reversible") = C_(V) (T_(1)-T_(2))`
If `w_(1),w_(2),w_(3)` and `w_(4)` are work done in isothermal, adiabatic, isobaric, and isochoric reversible processes, respectively then the correct sequence (for expansion) would be

Explanation

Although each of the above has same electronic distribution in bonding orbitals, nitrogenis inert because of non-polar nature of bond and high `N -= N` dissociation energy. Rest all `(CO, CN^(-), NO^(+))` are polar.
