A reactor is initially charged with 10 mol of CH4,50 mol of H2O, and 1 mol of H2. After setting up the temperature and pressure, the following reaction takes place: C2H4(g) + H20(g) CHA(9) + CO2(g) + 2H2(g) Considering that 90% of the reaction is completed a) Determine the limiting reactant b) What is the percentage excess of the other reactant? c) How much of the excess reactant will be left? d) How much CH4 will be formed? e) What is the extent of reaction? f) Determine the molar composition
