The rate of the reaction between hemoglobin (Hb) and carbonmonoxide (CO) was studied at 20°C. The following data werecollected with all concentration units in µmol/L. (Ahemoglobin concentration of 2.21 µmol/L is equal to 2.2110-6 mol/L.)

[Hb]0 (µmol/L) [CO]0 (µmol/L) Initial Rate (µmol/L · s)

[Hb]0 [C0]0 Initial rate
2.21 1.00 0.619
4.42 1.00 1.24
4.42 3.00 3.71

a) Determine the order of this reaction with respect to Hb and CO.

b) Determine the rate law.

c) Calculate the value of the rate constant.

d) what would be the initial rate for an experiment with [Hb]0 = 3.36 and [CO]0 = 2.40?
