A mixture of 30 mol% CO, 65 mol% H 2 , and 5 mol% N 2 is fed to a methanol (CH 3 OH) synthesis reactor, where the following reaction occurs: CO + 2H 2 CH 3 OH The reactor is at 200 C and 4925 kPa. The stream leaving the reactor is in equilibrium. If 100 kmol/h of the feed mixture is fed to the reactor, calculate the flow rates of all species leaving the reactor. What is the fractional conversion of CO? 2. The water gas-shift reaction CO + H 2 O CO 2 + H 2 reaches equilibrium quickly. Calculate K a vs. T in the range 1001000 C (step 100 C). Assuming that CO and steam are fed to a reactor at a stoichiometric ratio, calculate the mole fractions of CO and H 2 in the reactor outlet as a function of temperature in this range, if the reactor is at equilibrium. Plot your results ( y CO vs.vs....
