Chemistry - Chemical Kinetics Question with Solution | TestHub

Given rate law is $r=k[\text{NOBr}{]}^2$

Substituting the given values:

$k=1.62$

$[\text{NOBr}]=2\times 10^{-3}{\text{ mol L}}^{-1}=2\times 10^{-3}{\text{ mol dm}}^{-3}$

$r=1.62\times (2\times 10^{-3}{)}^2$

$r=1.62\times 4\times 10^{-6}$

$r=6.48\times 10^{-6}{\text{ mol dm}}^{-3}{\text{s}}^{-1}$

Answer: $6\cdot 48\times 10^{-6}{\text{ mol dm}}^{-3}{\text{s}}^{-1}$
