Fe2O3(s) +3CO(g) --------- 2Fe(s) + 3CO2(g).


a)

Given moles of Fe2O3 = 10 / 160 = 1 / 6 mol.

So moles of Fe = ( 2 / 6 ) mol . = 0.333 mole . Answer .


b ) 

Given .Moles of CO = 10 * / 28 Mol .

So moles of Fe = ( 2 *10 / 28 * 3 ) mol . = 0.238 mole .Answer .


3)

part ( b ) . have smaller product of Fe .


4 )

Fe2O3 is Limiting Reagent .

CO Is Excess Reagent .

No any amount left after reaction of limiting reagent .

Left amount of Excess Reagent = ( 10 / 28 - 1/2 ) mol.
