Gallium is gaining electron is false.
Gallium is being oxidized, for which it must lose electrons.

Answer:The false statements are:

1. Gallium is the catalyst.

2. Gallium is gaining electrons.

Explanation:

[tex]3Br_2 + 2 Ga\rightarrow 2 GaBr_3[/tex]

In the above reaction bromine is getting reduced as its oxidation states changes from 0 to -1.

Gallium is losing electrons to bromine due to which its oxidation state changes  from 0 to +3. Also catalyst doesn't show up in the product means they only effect rate of the reaction.

Hence ,gallium is not gaining electrons and also not a catalyst.
