Calculate the amount of PV work done. c2h4(g)+h2(g)-->c2h6(g) Express your answer using two significant figures. The addition of H2 to C=C double bonds is an important reaction used in the preparation of margarine from vegetable oils. If 36 mL of H2 and 36 mL of ethylene C2H4 are allowed to react at 1.6 atm , the product ethane C2H6 has a volume of 36mL.
