If ∆H is the change in enthalpy and the change in internal energy accompanying a gaseous reaction

Enthalpy is an ................ property

Select the correct set of statement/s :
I. Work done by the surrounding in case of infinite stage expansion is more than single stage expansion
II. Irreversible work is always greater than reversible work.
III. On an ideal gas in case of single stage expansion and compression system as well as surrounding are restored back to their original states
IV. If gas is in thermodynamic equilibrium is taken from state A to state B, by four successive single stage expansions. Then we can plot 4 points on the P - V indicator diagram

If W₁, W₂, W₃ and W₃ are work in isothermal, adiabatic, isobaric and isochoric reversible process, the correct order (for expansion) will be

The work done in ergs for the reversible expansion of one mole of an ideal gas from a volume of 10 litres to 20 litres at is

When Fe(s) is dissolved in aqueous HCl in a closed vessel the work done is

Hess law of heat summation includes

Ice - water mass ratio is material as 1 : 1 in a given system containing water in equilibrium with ice at constant pressure. If CP (ice) = CP(water) = 4.18 J mol^–1 K^–1 molar heat capacity of a such a system is

During winters, moisture condenses in the form of dew and can be seen on plant leaves and grass. The entropy of the system in such cases decreases as liquid posses lesser disorder as compared to gases. With reference to the second law, which statement is correct, for the above process ?

The enthalpy change for a given reaction at 298 K is – x J mol^–1 (x being positive). If the reaction occurs spontaneously at 298 K, the entropy change at that temperature
