(a) A sample of 1.0 mol of a monoatomic ideal gas is taken through a cyclic process of expansion and compression as shown in figure. What will be the value of `DeltaH` for the cycle as a whole?
(b) Which quantity out of `Delta_(r)G` and `Delta_(r)G^(Theta)` will be zero at equilibrium?

Text Solution

Verified by Experts

The net enthalpy change, `Delta H` for a cyclic process is zero as enthalpy change is a state function, i.e., `Delta H` (cycle) `= 0`
