Question

Hydrogen chloride gas and oxygen react to form water vapor and chlorine gas. What volume of chlorine would be produced by this reaction if of oxygen were consumed

Answer 1

Reaction of O₂ with HCl is as follow,

                                 4 HCl  +  O₂    →    2 H₂O  +  2 Cl₂

Let suppose we are given with 1 mole of HCl gas, Then,

According to eq,

  89.6 L (4 moles) of HCl when reacted produced  = 44.8 L (2 moles) Cl₂ gas

 

So,

                      22.4 L (1 mole) of HCl will produce  =  X L of Cl₂ gas

Solving for X,

                              X  =  (22.4 L × 44.8 L) ÷ 89.6 L

                              X  =  11.2 L of Cl₂ Gas
