Gaseous benzene reacts with hydrogen gas in presence of a nickel catalyst to form gaseous cyclohexane according to the reaction
A mixture of and excess 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 (by volume) present in the original volume is 1/y. The value of 'y' is

Correct answer
6
Step-by-step solution
Suppose initially, pressure of mm and that of mm.
So mm …(i)
After the reaction
Pressure of
Pressure of
Pressure of
Total pressure mm
Or mm …(ii)
Solving (i) and (ii) we get
mm
mm
Fraction of \left(g\right)= \dfrac{10}{60} = \dfrac{1}{6}
So mm …(i)
After the reaction
Pressure of
Pressure of
Pressure of
Total pressure mm
Or mm …(ii)
Solving (i) and (ii) we get
mm
mm
Fraction of \left(g\right)= \dfrac{10}{60} = \dfrac{1}{6}
