Problem

The reaction between NO2\text{NO}_2 and F2\text{F}_2 gives the following rate data at a certain temperature. What is the order of reaction with respect to NO2\text{NO}_2 and F2\text{F}_2 ?
[NO2]/mol dm−3[\text{NO}_2] / \text{mol dm}^{-3}[F2]/mol dm−3[\text{F}_2] / \text{mol dm}^{-3}Rate / mol dm−3min−1\text{mol dm}^{-3} \text{min}^{-1}
0.10.20.1
0.20.20.4
0.10.40.2
(1) NO2 order: first, F2 order: first (2) NO2 order: first, F2 order: second (3) NO2 order: second, F2 order: first (4) NO2 order: second, F2 order: second
