WebJul 6, 2024 · For the irreversible process the system is initially in equilibrium with the surroundings at state 1 just like the reversible process. The external pressure is then abruptly reduced to P 2 such that there is no time for the gas to initially expand or transfer heat with its surroundings. WebLook at en.wikipedia.org/wiki/Cyclic_voltammetry. In the cathodic scan, the scan voltage goes from more positive to less positive w.r.t. the reference potential. Then you get a reduction of B to Q. Then Q irreversibly goes to …

WebMay 22, 2024 · In thermodynamics, an irreversible process is defined as a process that cannot be reversed, process, that cannot return both the system and the surroundings to their original conditions. During irreversible process the entropy of the system increases. There are many factors that make a process irreversible: Presence of friction and heat … WebJul 23, 2024 · The key concept in a reversible process is that the system is in equilibrium with it's surroundings at every instant. A cyclic process is different: in a cyclic process, the initial and final state are the same.
