Question
Consider the reactions (data for 25°C), i) Pb(s) + CO(g) → PbO(s) + C(s) AG° = -51 kJ mol-1 ΔΗ-107 kJ mol-1 ii) 2 C(s) + 0,(g) → 2 CO(g) ΔΗ-221 kJ mol-1 AG° =-274 kJ mol-1 Which of the following statements is/are TRUE? Choose all that apply. Select all that apply A AS° for reaction 2 is -189 J K--mol-1. Both reactions are spontaneous at 25°C under standard conditions. Reaction 1 is spontaneous at 500°C C and 1 bar partial pressure of CO. Reaction 2 is spontaneous at 500°C and 1 bar partial pressure of O, and D CO.
