The thermite reaction was once used to weld rails:

(a) Using heat of formation data, calculate ΔH for this reaction.

(b) Take the specific heats of Al₂O₃ and Fe to be 0.77 and 0.45 J/g · °C, respectively. Calculate the temperature to which the products of this reaction will be raised, starting at room temperature, by the heat given off in the reaction.

(c) Will the reaction produce molten iron (mp Fe = 1535°C, ΔH_fus 5 270 J/g)?
