Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate

BPA‚ is a carbon based synthetic compound belonging to the group of diphenylmethane derivatives and bisphenols. The chemical formula for BPA is (CH3)2C(C6H4OH)2. BPA was first synthesized in 1891‚ and was recognized as a synthetic estrogen in the 1930s. The Food and Drug Administration (FDA) approved the use of BPA in 1960 to manufacture certain plastics and epoxy resins. This chemical compound of synthetic estrogen is used to harden plastics and resins‚ while keeping them lightweight. BPA is found
