Q. Which of the following statements are incorrect?
A) Rate of the reaction involving conversion of $ortho$ hydrogen to $para$ hydrogen $= - \frac{d\left\lbrack H_{2} \right\rbrack}{dt} = k\left\lbrack H_{2} \right\rbrack^{3/2}$
B) Rate of the reaction involving the thermal decomposition of acetaldehyde $= k\left\lbrack {CH}_{3}CHO \right\rbrack^{1/2}$
C) In the formation of phosgene from $CO\$and ${Cl}_{2},$ the rate of the reaction $= k\lbrack CO\rbrack\left\lbrack {Cl}_{2} \right\rbrack^{1/2}$
D) In the decomposition of $H_{2}O_{2},$ the rate of reaction $= k\left\lbrack H_{2}O_{2} \right\rbrack$
Explanation
(b)
Thermal decomposition,
${CH}_{3}CHO\overset{\ \ \ \ \ \mathrm{\Delta}\ \ \ \ \ }{\rightarrow}{CH}_{4} + CO$
$\frac{dx}{dt} = k\left\lbrack CH_{3}CHO \right\rbrack^{3/2}$
