Question

What volume in litre of HCl produced if 10L Cl_2 reacted with 20L H_2. H_2+Cl_2→2HCl ? a)10 b)20 c)30 d)15

Answer 1

a) `20 L`

Explanation:

Volume rates can be seen as equal to molar rates, that is: a certain volume of a gas always contains the same number of molecules (other conditions, like pressure and temperature, being equal).

So `10L` of `H_2` will react with `10L` of `Cl_2`
to form `2xx10L` of `HCl`
