Page 2 of 10 pages 1. THERMODYNAMICS (12 points total) Consider the formation of MgO (s). Mg (s) + 1/2 O 2 (g) MgO (s) Δ H r ° = -602 kJ/mol Δ S r ° = -108 JK -1 mol -1 . (Assume that Δ H r ° and Δ S r ° are independent of temperature.) (a) (6 points) Calculate Δ G r ° for the formation of MgO (s) at 0 ° C (273 K). Is the reaction spontaneous or non-spontaneous at 0
