Halogens react with hydrogen gas to form hydrogen halides.
Table 1 shows the relative speed of some of these reactions.
Fluorine also reacts with hydrogen gas.
Use Table 1 to predict the relative speed of the reaction between fluorine and hydrogen gas. Table 1
| Halogen | Relative speed of reaction |
|---|---|
| Fluorine | |
| Chlorine | Reacts very quickly |
| Bromine | Reacts slowly |
| Iodine | Reacts extremely slowly |
