Question

The "thermite reaction" is extremely exothermic - it has been used to produce liquid iron for welding. In this reaction powdered aluminum is allowed to react with metal iron(III) oxide, yielding solid iron and solid aluminum oxide. (Note: although the iron is produced in the molten state, if we wait for it to cool, then obviously it will be in the solid state.) What is the enthalpy change for this reaction if 2.00 mol of powdered aluminum is used? You will need to balance the reaction and use the standard enthalpies of formation.

Select one:

a. -687.3 kJ

b. -427.2 kJ

c. -1026.4 kJ

d. -852.0 kJ

e. -996.5 kJ

Explanation / Answer

c. -1026.4 kJ is correct
