In manufacture of chlorine, feed containing hydrochloric acid gas and air are fed to the reactor. the product gases leaving the reactor are found to contain 13.2% hcl, 6.3% 02, 42.9% n2, 30% cl2 and 7.6% h2o (by weight). calculate:
i) the percent excess air used.
ii) the composition of gases entering reactor
iii) the degree of completion of oxidation (conversion)
(hint: start solving by change the mass flow rate to mol flow rate first.)
