Calculate the standard enthalpy of formation of FeS2(s) at 600.

Calculate the standard enthalpy of formation of FeS2(s) at 600. °C from the following data at 298.15 K. Assume that the heat capacities are independent of temperature.

Substance S(rhombic) so, (g) FeS:(s) Fe(s) Fe,03(s) -824.2 AH, (kJ mol-) -296.81 3.02 7.48 2.72 CP,/R

You are also given that for the reaction 2FeS2(s) + 11/2O2(g) â†’ Fe2O2(s) + 4SO2(g).∆HoR = - 1655 kJ mol-1
