Question

In a chemical reaction A(g) is converted to B(g), following observation is made. Identify the incorrect statement(s).

• A. Chemical reaction can be represented as $\frac{1}{2}A\left(g\right)\to B\left(g\right)$.
• B. $t_{1/2}$ of the reaction is independent of initial partial pressure of A.
• C. Reaction must be complex reaction.
• D. Time of completion for the reaction is 40 minutes.

Answer 1

Answer: (B)

$t_{1/2}$ of the reaction is independent of initial partial pressure of A.

slope of $P^B=\frac{4}{10}$

slope of $I^A=\frac{2}{10}$

clearly $B$ is converting into $A$

rate of formation of $B$ is twice then the deformation rate of $A$ then clearly resultant rnn

$\frac{1}{a}A⟶B$ ( Statement $A$ is correct )

statement $B$ is wrong because only first order rnn $1s{t}_{1/2}$ does not depend on initial pressure ($B$ intersect )

molecularity is half so it must be a complex rnn.

rate of deformation is $\frac{2}{10}$ to $\frac{2}{10}\times t=8;t=40min$
