1. The problem statement, all variables and given/known data Consider a continuous, steady state process to produce hydrogen in which the following reactions take place: C6H12 + 6H2O -> 6CO + 12H2 (desired reaction) C6H12 + H2 -> C6H14 (undesired reaction) In the process 220 mol of C6H12 and 840 mol of H2O is fed into the reactor each hour. If the yield of H2 is 48% and the selectivity of H2 relative to C6H14 is 10.5: Which component is the limiting reagent? What is the % excess of the excess reagent? Calculate the molar flow rates of all the components in the outlet fas. Silicon (Si) is prepared for use in the semiconductor industry by reaction and separation in a two stage process as shown below. http://prntscr.com/idts4 The solid Si is reacted with gaseous hydrogen chloride (HCl) to form several polychlorinated silanes. If 100kg of Si (solid) is reacted, what mass of trichlorosilane (HSiCl3) is produced? 2. Relevant equations 3. The attempt at a solution If someone could start me off (the VERY, VERY start) as I don't understand this part of the question 'In the process 220 mol of C6H12 and 840 mol of H2O is fed into the reactor each hour. If the yield of H2 is 48% and the selectivity of H2 relative to C6H14 is 10.5:' it would be much appreciated.
