CH-1020 Chapter Notes - Chapter 12: Sodium Hydroxide, Jmol, State Function
Document Summary
Solutions and colligative properties molarity, aqueous solutions. Chemical kinetics how fast a reaction will happen. Spontaneous processes does(cid:374)"t care how fast a reaction goes. Absolute entropy and molecular structure bigger molecule, more entropy. For a spontaneous process, the total entropy of the universe, Suniverse, must increase. (the change in free energy, G, is used instead as it is easier to calculate. ) G tells about the position and direction of a reaction. Thermodynamics: standard conditions: 1 atm, 25 degrees c (room temp, tells us whether a process occurs, direction of process (rxn, phase change etc) Understand the implications of the second and third laws of thermodynamics. Relate g to h, s, temperature and spontaneity. Predict the spontaneity of a chemical reaction as a function of temperature. Use gf to determine whether a given reaction will be expected to occur (or be favored; spontaneous). Explain how g is related to useful work. Ch 12 terms to look up and know.
