Ethylene oxide is prepared by oxidation of ethylene. 100 kmol of ethylene and 100 kmol of O2 are charged to a reactor. The percent conversion of ethylene is 85 and percent yield of C2H4O is 94.12. Calculate the composition of product steam leaving the reactor. The reactions taking place are : C2H4 + ½ O2 > C2H4O C2H4 = 3 O2 → 2 CO2 + 2 H2O

What is the molar energy of combustion (in kJ/mol) of C7HO2 when 2.50 g of C7H6O2 burns completely in excess O2 gas at constant pressure, temperature 298 K and releases -30.9 kJ of energy? 2 C7H6O2 + 15 02 - 14 CO2 + 6 H20 1.59 x 105 kJmol-1 1.59 x 10 kJmol-1 O 1.59 x 103 kJmol¯1 1590 kJmol-1

A land-based vehicle will be an important part of any future exploration of the planet Mars. One proposed design for a Mars rover uses a methane gas fuel cell as its power supply. The methane fuel can be made on Mars using a chemical reaction that has been known for over 100 years the Sabatier methanation reaction: CO₂ (g) + 4H₂ (g) CH4 (g) + 2H₂O (g) AH = -165 kJ at 250°C Predict and explain, according to Le Chatelier's principle, THREE unique conditions required in a closed Sabatier reactor to produce the maximum amount of methane.
