Solution

The correct option is B $R a t e = k [C H_{3} O H]^{x} [O_{2}]^{y}$
$C H_{3} O H (g) + O_{2} (g) ⟶ C O_{2} (g) + 2 H_{2} O$
The order of the reaction is determined to experiment experimentally. We cannot predict the powers of the concentration terms in the rate law expression simply on the basis of stoichiometry as it can be complex reaction whose rate law depends on the slow-step.
$∴ r a t e = k [C H_{3} O H]^{x} [O_{2}]^{y}$
