Document Summary

Law of conservation of energy, internal energy and its relationship to temp. Intermediates are produced in one elementary process and consumed in another: rate-determining step is one elementary step much slower than the other. Chapter 12 properties of mixtures (12. 1 to 12. 5: solute, solvent, solubility (s) is max amount can dissolve, when solution forms, solute-solute and solvent-solvent attractions are replaced by solute- solvent attractions, only occurs if forces are similar. Which is most soluble in water, per mol: nacl, sucrose, olive oil or mercury = table sugar (has many. Oh bonds, lots interactions: solvation: process of surrounding a particle with solvent particles. Highest van"t hoff factor is cucl2 (sucrose is 1 since nonelectrolyte, h3po4 only one h dissociates: p = density x gravity x height = c r t, hg = mrt/mv so m = mrt/ghv. Chapter 16 (16. 1-16. 8: acid is proton donor, any species that donates h+ ion, base is proton acceptor, any species that accepts h+ ion.
