6. Which of the following statements is true concerning the reaction below? CH.(g) + N2(g) → HCN(g) + NH3(g): AH° = 164.1 kJ: AG° = 159.1 kJ at 298 K A) It is nonspontaneous at all temperatures. B) It is spontaneous at relatively low temperatures only. C) It is spontaneous at all temperatures. D) It is at equilibrium at 298 K. E) It is spontaneous at relatively high temperatures only.
