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 $∆ H$ for the cycle as a whole?

The net enthalpy change,

∆ H

for a cyclic process is zero as enthalpy change is a state function, i.e.,

∆ H (cycle) = 0
