Gaseous benzene reacts with hydrogen gas in the presence of nickel catalyst to give gaseous cyclohexane. A mixture of benzene vapour and hydrogen had a pressure of 60 mm Hg in vessel. After all benzene converted to cyclohexane, the pressure of the gas was 30 mm Hg in the same volume and at the same temperature. What fraction (by mole) of the original mixture was benzene?

Gaseous benzene reacts with hydrogen gas in presence of a nickel catalyst to form gaseous cyclohexane according to the reaction: C_(6)H_(6) (g) + 3H_(2) (h) rArr C_(6) H_(12) (g) A mixture of C_(6)H_(6) and excess H_(2) has a pressure of 60 mm of Hg in an unknown volume. After the gas has been passed over a nickel catalyst and all the benzene converted to cyclohexane, the pressure of the gas was 30 mm of Hg in the same volume and temperature. The fraction of C_(6)H_(6) (by volume) present in the original mixture is :
