WebChemical thermodynamics is the portion of thermodynamics that pertains to chemical reactions. The Laws of Thermodynamics First law: Energy is conserved; it can be neither created nor destroyed. Second law: In an isolated system, natural processes are spontaneous when they lead to an increase in disorder, or entropy. WebThe formula used to find the value of Activation Energy, E a is; K = Ae-Ea/RT Where K = Rate Constant A = Arrhenius Constant E a = Activation Energy R = Gas constant = 8.34J/K/mol =8.314/1000 KJ/K/mol = 2 cal/K/mol = 0.0821 lit atm/K/mol K = Ae -Ea/RT Taking log on both sides ln K = ln A – (E a /RT)ln e 2.303 log K = 2.303 log A – E a /RT cymbalta and double vision
