Vedclass · Answer

(B) The hydrogenation reaction of ethene is given by:$CH_{2}=CH_{2} + H_{2} \longrightarrow CH_{3}-CH_{3}$According to the stoichiometry of the reaction,$1 \ mole$ of ethene reacts with $1 \ mole$ of $H_{2}$ gas.Since volumes of gases are directly proportional to the number of moles at $	ext{S.T.P.}$,$0.5 \ dm^{3}$ of ethene will require $0.5 \ dm^{3}$ of dihydrogen for complete hydrogenation.

The volume of dihydrogen required for complete hydrogenation of $0.5 \ dm^{3}$ of ethene at $\text{S.T.P.}$ is (in $dm^{3}$)
