Question

In the equation below, which of the following is not true?

3 Br2 + 2 Ga 2 GaBr3

Bromine gas is being reduced.

Gallium is the catalyst.

Ga is the reducing agent.

Gallium is gaining electrons.

Answer 1

Answer:The false statements are:

1. Gallium is the catalyst.

2. Gallium is gaining electrons.

Step-by-step explanation:

`3Br_2 + 2 Ga\rightarrow 2 GaBr_3`

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.

Answer 2

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