I am conducting the reaction shown in the balanced equation below. The reaction generally proceeds in the liquid phase, and reactants A and B are both liquid reactants; W is a gas phase reactant which is bubbled through the liquid in order to initiate the reaction. A is very valuable, so I want to do everything I can to get it to react, so I feed the other reactants in excess. The reactor has three outlets; one for the solid phase products M and N, one for the liquid phase product D and any liquid reactants which do not react, and one for the gas phase products Y and Z and any left-over gas reactants.

1A (liquid) + 2B (liquid) +3W (gas) --> 3M (solid) + 2N (solid) + 1D (liquid) +1Y (gas) + 2Z (gas)

I also know...The molar flowrate of the solids outlet stream is 200% that of the molar flowrate of A into the system. The molar fraction of the product D in the liquid outlet stream is 0.125. The molar fraction of the reactant W in the gaseous outlet stream is 0.7.

a. What is the molar fraction of M in the solids stream?
b. What is the fractional conversion of A?
c. What is the fractional excess of B in the feed?
d. What is the fractional excess of W in the feed?
