Explanation / Answer

Answer 6) For the reaction , acetone +Br2---->products

Rate law gives,

Initial rate=k[acetone]^m *[Br2]^n where k=rate constant and n,m are the order of the reaction with respect to acetone and Br2 respectively.

putting the given data in the above equation,

4.00*10^-3 M/s=k*[1M]^m *[1M]^n .....................(1)

8.00*10^-3 M/s=k*[2M]^m *[1M]^n .....................(2)

8.00*10^-3 M/s=k*[2M]^m *[2M]^n .....................(3)

divide eqn (2) by (1),

2^1=(2)^m

m=1

now divide equation,(3) by (2),

1=(2)^n

log1=nlog2

n=0

now putting m=1 ,n=0 in eqn (1),

4.00*10^-3 M/s=k*[1M]

k=4.00*10^-3 s^-1

So rate equation, rate=k [acetone]
