perovskite: H°f = –1660.6 kJ/mol; quartz: H°f = – 910.7 kJ/mol; titanite: H°f = –2596.6 kJ/mol

Consider the reaction: CaTiO3 (perovskite) + SiO2 (quartz) = CaTiSiO5 (titanite) at the standard state (298.15 K and 1 bar). (5 pts)

i) Show whether the reaction is exothermic or endothermic.

ii) Will the product or the reactant be favored by an increase in temperature? Explain.
