For the elementary reaction M → N , the rate of disappearance of M...

For the elementary reaction

M \to N

, the rate of disappearance of

M

increases by a factor of

8

upon doubling the concentration of

M

. The order of the reaction with respect to

M

is

Options

A $4$
B $3$
C $2$
D $1$

Correct answer

B. $3$

Step-by-step solution

\dfrac{{r}_{1}}{{r}_{2}} = \dfrac{1}{8} = \dfrac{{\left[M\right]}^{n}}{{\left[2M\right]}^{n}} ⇒ n = 3
