For the reaction

4A(g) + 3B(g)

2C(g)

The following data were obtained at constant temperature:

 Experiment Initial [A] (mol/L) Initial [B] (mol/L) Initial Rate (mol/L · min) 1 0.100 0.100 5 2 0.300 0.100 45 3 0.100 0.200 10 4 0.300 0.200 90

Determine the reaction order with respect to each reactant.

 Reaction order for A: Reaction order for B:

Step 1

Consider order of reaction w.r.t [A] as m and order of reaction w.r.t [B] as n.

The rate expression would be,

Rate = k[A]m[B]n

Step 2

Order with respect to reactant A:
