We have studied three different forms of the Gibbs Helmholtz equation and we saw their applications that how we can use the Gibbs Helmholtz equation in calculating Gibbs's free energy. Previously in thermodynamics, we have learned about Entropy change and how can we determine the entropy change during- 1) Reversible transformation 2) Irreversible transformation 3) Reversible phase transformation 4) Irreversible phase transformation We have also learned about the Ehrenfest classification of phase transition where Ehrenfest classified first-order and second-order phase transitions. For the first-order phase transition: 1) G is continuous 2) The first derivative of G is discontinuous For the second-order phase transition: 1) G is continuous. 2) The first derivative of G is continuous. 3) The second derivative of G is discontinuous. So far, we have learned about Delta G and Delta S dependence on temperature and now it's time to learn how enthalpy change (Delta H) changes with temperature. And the equation that gives temperature dependence of Enthalpy change is known as Kirchhoff's equation. In the last lecture, we started the thermodynamics of the open system where chemical potential plays a very important role when we talk about CSIR-NET exam and GATE exam. We had seen the temperature dependence of chemical potential and the pressure dependence of chemical potential and the Gibbs-Duhem equation. Some topics are still left in thermodynamics and today we will cover Bomb Calorimetry Experiment in detail. --------------------------------------------------------------------------------------------------- ------------------------------------------------------------------------------------------------------------ DISCLAIMER: Copyright Disclaimer Under Section 107 of the Copyright Act 1976, the allowance was made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research.
