Hydrogen bromide is a highly reactive and corrosive gas used mainly as a catalyst for organic reactions. It is produced by reacting hydrogen and bromine gases together.

The rate is followed by measuring the intensity of the orange color of the bromine gas. The following data are obtained:

(a) What is the order of the reaction with respect to hydrogen, bromine, and overall?

(b) Write the rate expression for the reaction.

(c) Calculate k for the reaction. What are the units for k?

(d) When what is the rate of the reaction?
