In our first presentation of these concepts (Reference 2), we used the symbol C (for concentration) to describe the firstorder rate equations, but the different set of symbols A, Y, and C seem particularly appropriate here to represent the concentration of the three chemical components expressed in equation iii. The authors also consider that the minus sign is an essential part of the specific rate constant, although this is not the usual convention found in textbooks of physical chemistry. Nonetheless, equations ii and v are the form in which the equations are usually found.
