Given the Following Data, Determine the Rate Law for the Reaction

Given the following data, determine the rate law for the reaction
CH₃CHO(g) $\rightarrow$ CH₄(g) + CO(g) $\begin{array} { l } \text {Experiment }&\boldsymbol{P}_{\left(\mathrm{CH}_{3} \mathrm{CHO}\right) }&\text { Rate (mtorr/s) }\\&\text { (mtorr) }\\1 & 25.0 & 45.6 \\2 & 12.5 & 16.0\end{array}$

A) Rate = k
B) Rate = kP[CH₃CHO]
C) Rate = kP[CH₃CHO]^3/2
D) Rate = kP[CH₃CHO]^1/2
E) Rate = kP[CH₃CHO]²
