WebCarrying Processes in a Reversible Manner • ∆S. sys. can be easily measured through ∆S. sur. only for a reversible process. Therefore, if we need to determine ∆S. sys. in an irreversible (spontaneous) process we need to construct an artificial reversible process that would lead to the same final state, hence it would produce the same ...
