Vedclass · Answer

(B) The order of a reaction is an experimental quantity and can indeed have a fractional value. Thus,the Assertion is true.The order of a reaction is determined experimentally and cannot be deduced simply from the stoichiometric coefficients in a balanced chemical equation,as the reaction mechanism may involve multiple steps. Thus,the Reason is also true.However,the fact that the order is fractional (Assertion) is not explained by the fact that it cannot be determined from the balanced equation (Reason). Therefore,both are correct,but the Reason is not the correct explanation of the Assertion.

$Observation$	$[A] \ (mol \ L^{-1})$	$[B] \ (mol \ L^{-1})$	$Rate \ (mol \ L^{-1} \ sec^{-1})$
$1$	$0.1$	$0.1$	$2 \times 10^{-3}$
$2$	$0.2$	$0.1$	$4 \times 10^{-3}$
$3$	$0.1$	$0.2$	$8 \times 10^{-3}$

Assertion: The order of a reaction can have a fractional value.
Reason: The order of a reaction cannot be determined from the balanced chemical equation of a reaction.
