Q4. Ethene reacts with hydrogen in the presence of a finely divided nickel catalyst at a temperature of about 150C where Ethane is produced according to the reaction below Ni CH2=CH2 + H2 CH3-CH3 1 mole Ethene and 1.5 moles of Hydrogen are fed into the reactor at 20C and a total absolute pressure of 20.0 atm. The rector temperature is raised to 150C and held constant until the reaction is complete. Assuming ideal gas behaviour calculate the: a) the pressure when the reaction has gone to completion; and (5 Marks) b) the fractional conversion of Ethene when P = 18 atm (5 Marks) Ethene (CH2=CH2) Feeding of gases into Hydrogenator Ethane (CH3-CH3) Excess Hydrogen (H2) Hydrogen (H) Ni CH2=CH2 + H2 CH3-CH3 P1V1 niT1 = P2V2 n2T 2 (5+5 = 10 Marks) =
