0.5 mole each of two ideal gases A \(\left(\mathrm{C}_{\mathrm{v}, \mathrm{~m}}=\frac{5}{2} \mathrm{R}\right)\) and B (Cv,m = 3R) are taken in a container and expanded reversibly and adiabatically, during this process temperature of gaseous mixture decreased from 350 K and 250 K. Find ∆H (in cal/mol) for the process :
- –100 R
- –137.5 R
- –375 R
- None of these
Answer
(D) None of these
