From the rate expression for the following reactions, determine their order of reaction and the dimensions of the rate constant.
`CHCl_3 (g) + Cl_(2) (g) to "CCl"_(4) (g) + HCl(g), "Rate" = k [CH Cl_3 ] [Cl_2 ]^(1//2)`

Text Solution

Verified by Experts

Rate `= k [ CHCI_3 ] [CI_2]^(1//2)`
Order of reaction `= 1+ 1//2 = 1.5`
Dimension of `k = ("Rate")/( [CHCI_3] [CI_2]^(1//2) ) = ("mol L"^(-1)" s"^(-1) )/( ("mol L"^(-1) ) ("mol L"^(-1) )^(1//2) )`
`= "mol"^(-1//2)" L"^(1//2)" s"^(-1)`
