Document Summary

Introductory university chemistry ii (chem 102 / 105) Chemical kinetics log 1 = 0 log mn = log m + log n log xy = y log x. You may find the following mathematical formulas useful in this course: If ax = n, x = logan a0 = 1, log m = log m log n. Dx = ln x + constant x. Thermodynamics gives the energy change and the extent (chemical equilibrium) of a chemical reaction. The two are totally independent on each other. The area of chemistry that concerns reaction rates is called chemical kinetics. A graph of the concentration of no2, no and o2 plotted against time: Change in amount (or concentration ) of substance a. Concentration of a at t2 concentration of a at t1. For no2, the rate of reaction = - The negative sign indicates concentration decreases with time. From the graph; for the first 100 s,
