Irreversible expansion is gas expansion against constant external pressure. Also, it can be considered as an expansion that happens spontaneously without doing any work.

The equation for irreversible expansion is q = (mass)(heat capacity)(change in temperature). This will calculate how much energy is required to change the temperature of a substance.

The difference between irreversible and reversible expansion is that in irreversible, the reaction does not remain in thermodynamic equilibrium.

I'm still confused about the difference between reversible and irreversible equilibrium. The book gives an example of a piston. Can someone please explain it in the context of that?
