Problem: Ethene is converted to ethane by the reactionC2H4(g) + H2(g)     C2H6(g)C2H4 flows into a catalytic reactor at 25.0 atm and 300.°C with a flow rate of 1000. L/min. Hydrogen at 25.0 atm and 300.°C flows into the reactor at a flow rate of 1500. L/min. If 15.0 kg C2H6 is collected per minute, what is the percent yield of the reaction?

FREE Expert Solution

This problem requires that we use the ideal gas law first and then do stoichiometric calculations.


We will solve this problem through these steps:

  • Use the ideal gas law to find the moles of ethene and hydrogen.
  • Find the limiting reactant and theoretical yield.
  • Find percent yield using the actual and theoretical yield.


So, let’s start with ethene.
