From the rate expression for the following reaction, determine the order of reaction and the dimension of the rate constant.
\[\ce{C2H5Cl_{(g)} -> C2H4_{(g)} + HCl_{(g)}}\] Rate = k[C2H5Cl]

उत्तर
Given rate = k[C2H5Cl]
∴ Order of the reaction = 1
Dimension of k = \[\ce{\frac{Rate}{[C2H5Cl]}}\]
= \[\ce{\frac{(mol L^{-1} s^{-1})}{mol L^{-1}}}\]
= s−1
