# From the Rate Expression for the Following Reactions, Determine Their Order of Reaction and the Dimensions of the Rate Constants. - Chemistry

From the rate expression for the following reactions, determine their order of reaction and the dimensions of the rate constants.

C2H5Cl(g) → C2H4(g) + HCl(g) Rate = k [C2H5Cl]

#### Solution

Given rate = [C2H5Cl]

Therefore, order of the reaction = 1

Dimension of k = "Rate"/[C_2H_5Cl]

=("mol L"^(-1) s^(-1))/"mol L"^(-1)

= s-1
