The reduction of iron(III) oxide to iron metal is an endothermic process: Fe2O3(s) + 2 CO(g) → 2 Fe(s) + 3 CO2(g) ΔH = +26.3 kJ How many kilojoules of energy are required to produce 1.00 kilogram of iron metal?

Thus 234 kJ of energy are required to produce 1.00 kilogram of iron metal

Explanation:

To calculate the number of moles , we use the equation:

Putting values , we get:

   (1.00kg=1000g)

The balanced chemical reaction is:

Given :

Energy released when 2 moles of is produced = 26.3 kJ

Thus Energy released when 17.8 moles of is produced =

=

Thus 234 kJ of energy are required to produce 1.00 kilogram of iron metal
