  • A sample of 1.0 mol of a monoatomic ideal gas is taken through a cyclic process of expansion and compression, as shown in the figure. What will be the value of \Delta H for the cycle as a whole?

A sample of 1.0 mol of a monoatomic ideal gas is taken through a cyclic process of expansion and compression, as shown in the figure. What will be the value of \Delta H for the cycle as a whole?

Answers (1)

In case of a cyclic change, the value of \Delta H = 0 i.e. there is not going to be any change in the enthalpy.

The net change in enthalpy in a cyclic process is zero, i.e  \Delta H = 0 because it is a state function.

A cyclic process is a series of thermodynamic changes that return a system to its initial state. During a cyclic process, a system undergoes a series of expansions and compressions, absorbing and releasing heat, and performing work.
