Question 2

For the reaction between nitrogen(II) oxide and chlorine to produce nitrosyl chloride, 2NO + Cl₂→2NOCl, it is found that tripling the concentration of both reactants increases the rate by a factor of 27. If only the concentration of chlorine is tripled, the rate increases by a factor of 3. The overall order of this reaction is
