Consider the reaction represented by the equation:

CH₃Cl(g) + H₂O(g) —→ CH₃OH(g) + HCl(g)

These kinetic data were obtained for the given reaction concentrations:

Answer the following question based on these data :

Which of the following is/are correct :-

Options:(select one or more)

Answer:

B, D

Solution:

$C H_{3} Cl (g) + H_{2} O (g) R a t e \frac{r _{1}}{r _{2}} \frac{1}{2} \frac{2}{8} \frac{1}{4} R a t e ⟶ C H_{3} OH (g) + HCl (g) = - \frac{d [ C H _{3} Cl ]}{dt} = K [C H_{3} Cl]^{M_{1}} [H_{2} O]^{M_{2}} = \frac{[ H _{2} O ] ^{M_{2}} [ C H _{3} Cl ] ^{M_{1}}}{[ H _{2} O ] ^{M_{2}} [ C H _{3} Cl ] ^{M_{1}}} = (\frac{1}{2})^{M_{2}} ⟹ M_{2} = 1 = (\frac{2}{4})^{M_{1}} = (\frac{1}{2})^{M_{1}} ⟹ M_{1} = 2 = K [C H_{3} Cl]^{1} [H_{2} O]^{2}$
