A company can make compound X by two different routes. Table gives data for the two routes.
Table: Data for two industrial routes to compound X
| Route | Percentage atom economy in % | Percentage yield in % | Rate of reaction | By-product |
|---|---|---|---|---|
| A | 92 | 35 | slow | no use |
| B | 48 | 88 | fast | sold as a fertiliser |
Explain which route the company should choose. Use the data in Table.
Give one piece of information, other than the data in Table, that the company would need before choosing a route.
