Consider the following reaction: Fe2O3 + 3CO ---- 2Fe + CO2 (a)with the reaction and quantities given, how many moles of Fe are formed? (B) if 2 moles of Fe2O3 are reacted with 3 miles of CO, what is the limiting reactant?

Question

Consider the following reaction: Fe2O3 + 3CO ----> 2Fe + CO2 (a)with the reaction and quantities given, how many moles of Fe are formed? (B) if 2 moles of Fe2O3 are reacted with 3 miles of CO, what is the limiting reactant?

1- balance the equation

anonymous · Answer

a) 2 moles  2Fe as the equation indicate 
b) limiting reaction 
form the equation : 1 mole of Fe2O3 required 3 moles CO, so if Fe2O3 increases and CO not. the limiting factor is CO because all 3 moles has been used for the first mole of Fe2O3 and nothing left for the second mole.
