Problem

For the reaction 2 NO(g) + O₂(g) → 2 NO₂(g), the experimentally determined rate law is rate=k[NO]2[O2]\text{rate} = k[\mathrm{NO}]^2[\mathrm{O_2}]. If the concentration of NO is tripled while the concentration of O₂ and the temperature remain unchanged, by what multiplicative factor will the reaction rate change?
