1.	Two moles of a triatomic linear gas (neglect vibration degree of freedom) are taken through a reversible process ideal starting from A as shown in figure. The volume ratio `(V_(B))/(V_(A))=4`. If the temperature at A is `-73^(@)C`, then : Work done by the gas in AB process is : `6.16` kJ `308.3` kJ `9.97` kJ 0 J (ii) Total enthalpy change in both steps is :A. 3000 RB. 4200 RC. 2100 RD. 0
Answer» Correct Answer - B::C (i) (c) `w=-P.DeltaV=-nRDeltaT=-2xx8.314xx600` `=-9.97kJ` (ii) (b) `DeltaH_("total")=DeltaH_(AB)+DeltaH_(BC)=nC_(p,m)DeltaT+0` `=2xx(7)/(2)xxRxx(800-200)` = 4200 R
