Chemical Kinetics - Result Question 29

####29. During the kinetic study of the reaction, $2 A + B \to C + D$ , following results were obtained:

$Unknown environment 'tabular'$ \ \hline I & 0.1 & 0.1 & $6.0 \times 10^{- 3}$ \ \hline II & 0.3 & 0.2 & $7.2 \times 10^{- 2}$ \ \hline III & 0.3 & 0.4 & $2.88 \times 10^{- 1}$ \ \hline IV & 0.4 & 0.1 & $2.40 \times 10^{- 2}$ \ \hline \end{tabular}

Based on the above data which one of the following is correct?

[2010]

(a) $r a t e = k [A]^{2} [B]$

(b) rate $= k [A] [B]$

(d) $r a t e = k [A] [B]^{2}$

Show Answer

Solution:

(d) In case of (II) and (III), keeping concentration of $[A]$ constant, when the concentration of $[B]$ is doubled, the rate quadruples. Hence, it is second order with respect to B. In case of I & IV, keeping the concentration of [B] constant, when the concentration of $[A]$ is increased four times, rate also increases four times. Hence, the order with respect to $A$ is one. hence

$Rate = k [A] [B]^{2}$
