(a) Finding the individual and overall orders. For reactant A (red): Expts 1 and
2 show that when the number of particles of A doubles (from 2 to 4), with the
number of particles of B constant (at 2), the rate doubles (from 0.531024 mol/Ls to
1.031024 mol/Ls). Thus, the order with respect to A is 1. For reactant B (blue):
Expts 1 and 3 show that when the number of particles of B doubles (from 2 to 4), with
the number of particles of A constant (at 2), the rate quadruples (from 0.531024
mol/Ls
to 2.031024 mol/Ls). Thus, the order with respect to B is 2. The overall order is
1 1 2 5 3.
