Well, we must know by experiment that the process

#2"H"_2"O"_2(aq) -> "O"_2(g) + 2"H"_2"O"(l)#

is a first order process... hence, the units follow. Write the rate law, giving the initial rate of reaction as a function of the rate constant #k# and concentration #[" "]#.

#r(t) = k["H"_2"O"_2]#

#"M"/"s" = [???]cdot"M"#

#=> k# is in #bb("s"^(-1))#.
