Fixed-time method for uncatalyzed reactions. (a) Variation of [P] as a function of time for different initial concentrations of [A]0. (b) Variation of amount of P formed at fixed time tf with initial concentration of A.
Variable-time method for uncatalyzed reactions. (a) Variation of [P] as a function of time for various initial concentrations of [A]0. (b) Variation of 1t[P]f required to reach a fixed value of product formed [P]f with initial concentration of A.
