The thermite reaction was once used to weld rails: 2Al (s) + Fe2O3 (s) Al2O3 (s) + 2Fe (s) a) Using heat of formation data (see your textbook), 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) What assumption(s) do you have to make in answering part b)? d) Will the reaction produce molten iron (melting point Fe = 1535°C, ΔHfus = 270 J/g) ?
