Problem
Ethene reacts with molecular hydrogen according to the equation C₂H₄(g) + H₂(g) → C₂H₆(g) A reaction mixture is prepared with the following initial concentrations: [C₂H₄]₀ = 0.100 M [H₂]₀ = 0.120 M [C₂H₆]₀ = 0 M During the reaction the concentration of H₂ is monitored. The data are shown below.| Time (s) | [H₂] (M) |
|---|---|
| 0 | 0.120 |
| 40 | 0.096 |
| 80 | 0.072 |
