Expert Solution
Step 1

For the reaction: 

C2H4(g) + H2(g) →C2H6(g)

Hydrogen gas behaves as the excess reactant as it is taken in excess.

On the other hand, ethylene acts as the limiting reactant, so, the amount of ethylene will decide the yield of the product formed.

The observed yield =3.46 g
