Chemical change
- 02Chemical equilibriumClosed system, equal forward and reverse rates. Le Chatelier. K_c.
- 03Acids and basesArrhenius, Lowry-Brønsted. Strong vs weak. pH = −log[H₃O⁺]. Hydrolysis of salts.
- 04ElectrochemistryGalvanic vs electrolytic. Table of reduction potentials. E°cell = E°cathode − E°anode.
- 06Rates of reactionCollision theory: particles must collide with enough energy and the right orientation. Temperature, concentration, surface area and a catalyst change the rate, not the balanced equation.
