A manufacturer is choosing between two routes for making the same waterproofing chemical. Demand for the chemical is high and the starting materials are cheap.
| Route | Atom economy / % | Percentage yield / % | Production rate / kg h−1\mathrm{kg\ h^{-1}}kg h−1 |
|---|---|---|---|
| C | 84 | 58 | 14 |
| D | 61 | 90 | 30 |
Explain which route the manufacturer should choose. Use all the information in the table.
