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.

Initial concentration of $A$ $(M)$	Initial concentration of $B$ $(M)$	Initial Rate $(M \cdot s^{-1})$
$1$	$10$	$100$
$1$	$1$	$1$
$10$	$1$	$10$

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.

For the reaction $A + B \rightarrow C$, we have the following data:
Initial concentration of $A$ $(M)$ Initial concentration of $B$ $(M)$ Initial Rate $(M \cdot s^{-1})$
$1$ $10$ $100$
$1$ $1$ $1$
$10$ $1$ $10$

The order of the reaction with respect to $A$ and $B$ are:

Rate of reaction is $r_1 = k[A]^a[B]^b$. If the concentration of $A$ is doubled and $B$ is halved,the new rate is $r_2$. What is the value of $\frac{r_2}{r_1}$?

For the reaction $2 \ NOBr_{(g)} \rightarrow 2 \ NO_{(g)} + Br_{2_{(g)}}$,the rate law is $r = k[NOBr]^{2}$. If the rate constant is $1.62 \ M^{-1} \ s^{-1}$ and the concentration of $NOBr$ is $2.00 \times 10^{-3} \ M$,what is the rate of reaction?

Why can’t molecularity of any reaction be equal to zero?
