Mole Balances Chap. 1 The rate law is an k,C, -r4 = - al~ebra~c equation. I +klCA For a given reaction. the particufar co-xentrarion dependence that the rate law follows (i.e.. -r, = kc, or -rA = kc; or ... ) must be determined from exper- irnenral observation. Equation (1-2) states that the rate of disappearance of A i h equal to a rate constant k (which is a function of temperature) times the square The convention of the concentration of A. By convention. r, is the rare of formation of A; con- sequently. -,-, is the rate uf disappearance of A. Throughout this book. the phrase mte qf gerlerution means exact1 y the same as the phrase rntr qf'jiwmn- tion, and these phrases are used interchangeably. 1.2 The General Mole Balance Equation To perform a mole
