CIA Demonstration: The Thermite Reaction (6.2.2)

Question 1

• The thermite reaction is a highly exothermic reaction between aluminum metal
and iron(III) oxide (rust).

Answer 1

• The thermite reaction is a highly exothermic reaction between aluminum metal
and iron(III) oxide (rust).

Question 2

The thermite reaction is a highly exothermic reaction
between aluminum metal (Al) and iron(III) oxide
(rust, Fe2O3).
The products of the thermite reaction are aluminum
oxide (alumina, Al2O3) and molten iron (Fe).
The standard enthalpy change (∆H°) of this
reaction is –848 kJ. This extremely negative
number indicates that the thermite reaction is
extremely exothermic—a great deal of heat is given
off to the surroundings.
