Totally irreversible
WebIrreversible and Quasi-Reversible Systems For irreversible processes (those with sluggish electron exchange), the individual peaks are reduced in size and widely separated (Figure … WebThe total entropy, which is a summation of entropy of the system and entropy of the surrounding, is a determinant for the reversibility. The sign of total entropy determines if the process is reversible, spontaneous, or not spontaneous but need stimulus. As an exercise, let’s calculate the total entropy, the entropy of the universe for the ...
