A gaseous system is initially characterised by 500 mL volume and 1 atm pressure at 298 K. This system is allowed to do work as In isobaric conditions it expands to 800 mL resulting a decrease in pressure and temperature to 0.6 atm and 273 K respectively. (ii) In adiabatic conditions it is allowed to expand upto 800 mL and results a decrease in pressure and temperature to 0.6 atm and 273 K respectively. If Gibbs energy change in (i) is `DeltaG_(a)` and in (ii) is `DeltaG_(b)`, then what will be the ration of `(DeltaG_(a))/(DeltaG_(b))`?

1.	A gaseous system is initially characterised by 500 mL volume and 1 atm pressure at 298 K. This system is allowed to do work as In isobaric conditions it expands to 800 mL resulting a decrease in pressure and temperature to 0.6 atm and 273 K respectively. (ii) In adiabatic conditions it is allowed to expand upto 800 mL and results a decrease in pressure and temperature to 0.6 atm and 273 K respectively. If Gibbs energy change in (i) is `DeltaG_(a)` and in (ii) is `DeltaG_(b)`, then what will be the ration of `(DeltaG_(a))/(DeltaG_(b))`?
Answer» Correct Answer - B `(DeltaG_(a))/(DeltaG_(b))=1`, as Gibbs energy is a state function and intial and final states are same in (i) and (ii).
