For the gaseous reaction `H_(2)+ CI_(2)rarr 2HCI`
If `40ml` of hydrogen completely reacts with chlorine then find out the required volume of chlorine and volume of produced `HCI` ? .

Explanation

According to Gay Lussac's Law :
`H_(2)+Cl_(2)rarr2HCl`
`:' ml` of `H_(2)` will react will `1ml` of `Cl_(2)` and `2ml` of `HCl` will produce
`:. 40ml` of `H_(2)` will react with `40ml` of `Cl_(2)` and `80ml` of `HCl` will produce.
required vol. of `Cl_(2)=40ml`, produced vol. of `HCl=80 ml`
