Problem
The oxidation of nitric oxide by oxygen proceeds by the overall stoichiometry 2 NO(g) + O₂(g) → 2 NO₂(g). Kinetic studies show the rate is first order in NO and first order in O₂. The experiment is run twice using identical initial concentrations but at two different temperatures. The data are summarized below. [NO]₀ = 0.050 M [O₂]₀ = 0.020 M| Temperature (K) | Initial rate (mol·L⁻¹·s⁻¹) |
|---|---|
| 298 | 7.5 × 10⁻⁴ |
| 320 | 1.6 × 10⁻³ |
