Document Summary
Reaction rate is proportional to one concentration p and a = [p] and [a] at any given time k = 1st order rate constant. = [a] at time zero a constant ao. Theoretically it doesn"t matter if we measure depletion of substrate (a) or appearance of product (p). But experimentally this doesn"t apply usually your [a] is very large, and p is very small (easier to see small changes in) so it"s more accurate and precise to measure p. V = ka specifies that rate is proportional to the concentration of a. So when t = 0, then a = ao and p = 0 a + p = a0 at. Reaction rate is proportional to the product of 2 concentrations, or the square of one concentration - i. e. rate = a x b or rate = a2 k = 2nd order rate constant integrated:
