If the rate of reaction,

$2{\mathrm{SO}}_2\left(g\right)+{\mathrm{O}}_2\left(g\right)\stackrel{{\mathrm{Pt}}^{ }}{⟶}2{\mathrm{SO}}_3\left(g\right)$ is given by :

$\text{ Rate }=\mathrm{K}\frac{\left[{\mathrm{SO}}_2\right]}{{\left[{\mathrm{SO}}_3\right]}^{1/2}}$

Which statements are correct?

The general response order is $+1/2\{1-1/2=1/2\}$. As the product ${\mathrm{SO}}_3$builds up, the reaction slows down. The concentrations of ${\mathrm{SO}}_2$ and ${\mathrm{O}}_2$ affect the rate of reaction.
The concentration of reactants has a direct relationship with the rate of a reaction.
