Chemistry is defined as the systematic investigation of the properties, structure, and behavior of matter and the changes matter undergoes. This general definition raises many questions. These questions are answered in the study of chemistry. Terms and basic concepts that help in understanding chemistry will be discussed in this chapter.

number of formula units initially dissoved in soln Rate law expression. The sum (x+ y) gives the overall order of the reaction: rate = k[A]x[B]y Relationship between concentration and time for a first-order reaction: ln [A]o [A] = kt Equation for the graphical determination of k for a first-order reaction: ln [A] = -kt + ln [A]o
