if the rate law for the following reaction is found to be rate = k (sqrt (Cl2)) x (HCCl3)

what are the units for the rate law constant (k)?

Rate is always M/s.

So if we have rate = k sqrt(Cl2) x HCCl3

M/s = k sqrt(M) * M

M/(s*M*sqrt(M)) = k

k = 1/(s*sqrt(M))

Thank you, was wondering why rate is = M/s but i reasoned that since Rate = k in 0 order and 0 order has the units M/s that thus rate would be M/s

Thanks

That works.

Also though, you're considering the rate of formation of a product.. so you want to figure out how much product (M) is produced per second (s) so M/s.
