Example 4.11. Given the Rxn.: C2H2 + 2H2 C2H6 At the beginning of the process, 20 kg-mol of acetylene, 40 kg-mol of hydrogen, and 20 kg-mol of CzHs are charged into the reactor. Twenty (20) minutes later, 30 kg-mol of hydrogen reacts. Determine the compositions of the input stream and of a mixture in the reactor at the 20th minute. CaHa = 20 kg-mol Ha = 40 kg-mol Cahe = 20 kg-mol t = 0 Cat=x kg-mol H = 40-30 kg-mol CH-y ko-mol t = 20 min
