Question

Fundamentals of Material Balances where the numerical values of the stoichiometric coefficients (-1, -3, and 2) are understood to have units of mol/s. We accept such practice as inevitable but urge caution in its use. f The oxidation of ethylene to produce ethylene oxide proceeds according to the equation 2C2H4+O2 2C2H4O The feed to a reactor contains 100 kmol C2H and 100 kmol O2. 1. Which reactant is limiting? 2. What is the percentage excess of the other reactant? 3. If the reaction proceeds to completion, how much of the excess reactant will be left; how much C2H4O will be formed; and what is the extent of reaction? CeH4 4. If the reaction proceeds to a point where the fractional conversion of the limiting reactant is 50 %, how much of each reactant and product is present at the end, and what is the extent of reaction? 5. the reaction proceeds to a point where 60 kmol of O2 is left, what is the fractional conversion of CH? The fractional conversion of O2? The extent of reaction?
