In the process for the manufacture of chlorine by direct oxidation of hcl with air over a catalyst to form cl2 and h2o (only), the exit product is composed of mole fractions of cl2 (21.4%), h2o (21.4%), and n2 (45.0%) – the remainder is hcl and o2. calculate and /or identify: (a) the limiting reactant? (b) the percentage excess reactant? (c) the degree of completion of the reaction? (d) the extent of reaction?
