  1. Chapter 14

  2. Integrated Rate Laws First-Order: ln(ct/c0) = -kt Second-Order: (1/ct) - (1/c0) = +kt

  3. Arrhenius Equation Activation energy measured by comparing rates at different temperatures k = Ae-Ea/RT k2/k1 = (Ae-Ea/RT2)/(Ae-Ea/RT1) = e-Ea/RT2-(-Ea/RT1) k2/k1 = e-(Ea/R)(1/T2 - 1/T1) ln(k2/k1) = -(Ea/R)(1/T2 - 1/T1)
