The reaction 2A + B2 $\to$ 2AB is an elementary reaction.
For a certain quantity of reactants, if the volume of the reaction vessel is reduced by a factor of 3, the rate of the reaction increases by a factor of ____________. (Round off to the Nearest Integer).
Answer (integer)
27
Solution
Let initial concentration of A & B is a & b<br><br>Rate = $K{[A]^2}{[{B_2}]^1}$<br><br>${r_1} = K{\left( {{a \over V}} \right)^2}{\left( {{b \over V}} \right)^1}$<br><br>${r_2} = K{\left( {{{3a} \over V}} \right)^2}{\left( {{{3b} \over V}} \right)^1}$<br><br>$\left( {{{{r_2}} \over {{r_1}}}} \right) = 27$
