Consider a process in which a 2-mol sample of a certain gas is heated reversibly from 275 K to 375 K under a constant pressure of 1 bar, and the entropy change for the gas is ∆S = 13.3 J/K. What will be the value of ∆S for a process in which the same gas sample is heated irreversibly from 275 K to 375 K under a fixed pressure of 1 bar?
