【正文】 NTU ME . Ma Department of Mechanical Engineering National Taiwan University, Taipei, Taiwan November, 2023 臺(tái)灣大學(xué)機(jī)械工程系能源環(huán)境實(shí)驗(yàn)室 ? Maximum electric work (Wel) at constant temp. and pressure is given by Gibbs free energy: ? n is no. of electrons ? F is Farady’s constant ? E is ideal potential of the cell ? Besides, Gibbs’ free energy can be written as: ? ?H is enthaply change ? ?S is entropy change ? T?S represents the unavailable energy resulting from the entropy change At constant pressure, the specific entropy at temperature T is given by It than follows that, ? The Gibbs’ free energy can be expressed by the equation ? For the generation reaction, ? Substituting the equation into then, This is general form of the Nerne
