I need some help with some questions regarding kinetics

1) (a) Write the rate law for the following reaction using x, y, and z for the order of the individual components:

5Br- (aq) + BrO3- (aq)+ 6H+ (aq)  3Br2 (l) + 3H2O (l)





(b) Determine the individual orders and overall order using the following
experimental data:


Br- (aq) (M) BrO3- (aq) (M) H+ (aq) (M) Rate (M/s)
0.33---- 0.33---- -------0.33---- 4.3x10-4
0.33---- 0.66---- -------0.33---- 4.3x10-4
0.33---- 0.66---- -------0.66---- 1.7x10-3
1.32---- 0.66---- -------0.66---- 6.8x10-3

Order of Br- (aq) = 1st

Order of BrO3- (aq) = 2nd

Order of H+ (aq) = 2nd

Overall order = 5th order

Is this correct?

(c) What are the units of k for this reaction?
