Question

Which reaction will be faster? h+(aq)+cl-(aq) or h2(g)+cl2(g) why?

Answer 1

Hello!

I believe that h+(aq)+cl-(aq) would react faster because it has less molecules to react.

Answer 2

Step-by-step explanation:

It is known that in an aqueous (liquid) solution the atoms are somewhat closer together as compared to the atoms present in a gas.

So, in an aqueous solution there will be less number of collisions between the atoms.

On the other hand, molecules of a gas are held by weak intermolecular forces. So, they are able to move rapidly from one place to another with more number of collisions.

Hence, we can conclude that the reaction
`H_(2)(g) + Cl_(2)(g)` will be faster.
