Iron(III) oxide reacts with carbon monoxide according to the equation:
Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)
A reaction mixture initially contains 23.00 g Fe2O3 and 16.00 g CO.

Once the reaction has occurred as completely as possible, what mass (in g) of the excess reactant is left?

Solutions

Expert Solution

Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)

no of moles of Fe2O3    =   W/G.M.Wt

                                         = 23/159.69   = 0.144 moles

no of moles of CO          = W/G.M.Wt

                                       = 16/28   =0.57 moles

Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)

1 mole of Fe2O3 react with 3 moles of CO

0.144 moles of Fe2O3 react with = 3*0.144/1   = 0.432 moles of CO

CO is excess reactant

The no of moles of excess reactant left after complete the reaction = 0.57-0.432   = 0.138 moles

The amount of excess reactant left after complete the reaction = no of moles * gram molar mass

                                                                                                      = 0.138*28   = 3.864g of CO >>answer
