A manufacturer investigates the effect of catalyst X on a reversible reaction that makes product Y. The temperature and pressure are kept the same in both experiments. The results are shown in the table.
| Experiment | Catalyst X added | Time to reach equilibrium (min) | Product Y at equilibrium (%) |
|---|---|---|---|
| 1 | No | 80 | 42 |
| 2 | Yes | 20 | 42 |
Explain what the results show about the effect of catalyst X on the reaction.
