1. With initial concenration of A and B of 0.04 mol/L, the rate of formation of AB is measured at 0.005 mmol/(Ls). When the initial concentration of A is raised to 0.07 mol/L, with that of B the same as before, the rate of formation of AB increases to 0.015 mmol/(Ls). What is the order of reaction for A?

2. The reaction is found to be third order overall; what is its order in B?

3. If the initial concentration of B is changed to 0.08 mol/L, while that of A is reduced to 0.02 mol/L, what will be the new rate of formation of AB?

4. For a certain set of initial concentrations of A and B, it takes 10s to produce 0.1 mmol of AB at 20 deg celcius and 150s at 0 deg celcius. What is the ratio of the rate at 20 deg celcius to that at 0 deg celcius?
