Document Summary

Week 13 lecture 1: principles of chemical equilibrium. !1: depending on m, n, g, h, usually not unites, thermodynamic equilibrium constant in solution, activity (a): thermodynamic concept introduced by lewis, dimensionless ratio referred to a chosen reference state. Celsius: 1 cal = 4. 184 j, heat capacity (c, quantity of heat required to change the temp of a system by one degree celsius, molar heat capacity cp,m: system is a mole of substance. !1: speci c heat capacity or speci c heat (cp): the system is 1g of substance. !2: temp in reaction mixture usually changes during reaction so mixture must be returned to initial temp before we can assess how much heat is exchanged w/ surroundings. Thursday, january 25, 2018: standard entropy of change of reactions, so, so = [ vp so (products) - vp so (reactants)] Week 4 lecture 7: entropy and gibbs free energy. Week 5 lecture 9: entropy and gibbs energy.
