Question

Substance which acts as catalyst in the reaction H2+Cl2—> 2HCl​

Answer 1

Answer:

C12 is the answer of your question

Answer 2

$\huge\mathbb\pink{Answer}$

It must be H2 + Cl2 => 2HCl…

1 atom of Hydrogen reacts with 1 atom of Chlorine and form 2 molecules of Hydrochloric acid due to the presence of 2 atoms of both the substances.

(i.e. H2 and Cl2)

And this type of reaction is known as redox reaction..

Reason:

Hydrogen shows electron loss thereby getting oxidised and chlorine accepts the electrons lost by hydrogen thereby getting reduced!

• H2 → 2 H(+) + 2 e(-)

• Cl2 + 2 e(-) → 2 Cl(-)

Hope it's helps you :)
