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

Question

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