Tila) transform to Ti(ß) at 882 °C, with a heat of transformation equal to 830 cal. mol-1. Calculate the enthalpy change when Ti(B) at 1400 °C is oxidized by pure 02(g) isothermally to form Ti02(s) at 1400 °C. (20 %) AHf,298 K o (Ti02) = -225.5 kcal. mol-1 cp(Ti, a) = 5.48 + 2.25 x 10-3T cal. mol-1.K-1 cp(Ti, B) = 6.91 cal. mol-1.K-1 cp(Ti02, s) = 18 + 0.28 x 10-37 - 4.35 x 1057-2 cal. mol-1.K-1 cp(02, g) = 7.16 + 1.0 x 10-3T - 0.4 x 1057T-2 cal. mol-1.K-1 Tila) transform to Ti(ß) at 882 °C, with a heat of transformation equal to 830 cal. mol-1.
