For a reaction involving substances $x$,$y$,and $z$,if the overall order of the reaction is $0.5$,which of the following rate laws is applicable?

  • A
    Rate $= K [C_x] [C_y] [C_z]$
  • B
    Rate $= K [C_x]^{0.5} [C_y]^{0.5} [C_z]^{0.5}$
  • C
    Rate $= K [C_x]^{1.5} [C_y]^{-1} [C_z]^0$
  • D
    Rate $= K [C_x] [C_z]^0 / [C_y]^2$
