Webopposite of each other [(∆Ssys (+), ∆Ssurr (−) or vice versa], the process may or may not be spontaneous. 3. ∆Ssurr is primarily determined by heat flow. This heat flow into or out of the surroundings comes from the heat flow out of or into the system. In an exothermic process (∆H < 0), heat flows into the surroundings from the system ... 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 ...
