Chemical Kinetics - Result Question 6

####6. In a reaction, $A + B \to$ Product, rate is doubled when the concentration of $B$ is doubled, and rate increases by a factor of 8 when the concentrations of both the reactants $(A$ and $B$ ) are doubled. Rate law for the reaction can be written as :

[2012]

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

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

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

Show Answer

Solution:

(d) According to statement given in the question, it is clear that

$r \propto [A]^{2} and r \propto [B]$

That means, order of reaction with respect to $B$ is 1 and w.r.t $A$ is 2 .

Hence, Rate $= k [A]^{2} [B]^{1}$
