ChemistryEasysingle choice

If doubling the concentration of a reactant 'A' increases the rate 4 times and tripling the concentration of 'A' increases the rate 9 times, the rate is proportional to

Options:

Answer:

Solution:

Based on rate law, rate of reaction depends on concentration of reactant with power of concentration term same as order of reactant.
$R a t e = {[A]}^{n} {[B]}^{m}$
$\begin{array}{l} {[A]}^{n} = 2^{2} = 4, \\ {[B]}^{m} = 3^{2} = 9 \end{array}$
