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) to 2HCl`
`therefore` 1 ml of `H_(2)` will react will 1 ml of `Cl_(2)` and 2 ml of HCl will produce.
`therefore` 40 ml of `H_(2)` will react with 40 ml of `Cl_(2)` and 80 ml of HCl will produce required vol. of `Cl_(2)=40` ml , produced vol. of HCl=80 ml
