Question

Sodium hypochlorite is formed according to the reaction:
2NaOH + Cl2 → NaOCl + NaCl + H2O
In a continuous reactor, bubbling Cl2 through a concentrated solution (40% by mass) of
NaOH. Suppose that the solution of NaOH in water is fed at a rate of 1000 kg / h and the gas Cl2,
a ratio of 10 kgmol / h.
a) Calculate the degrees of freedom, assuming the conversion is specified.
b) Calculate the reactor outlet composition, assuming a conversion of 100% of the reactant
limiting.
c) Calculate the reactor outlet composition, assuming a conversion of 60% of the reactant
limiting.
