Without doing any calculations, determine the signs of S sys and S sur r for each chemical

Question:

Without doing any calculations, determine the signs of ΔS_sys and ΔS_sur_r for each chemical reaction. In addition, predict under what temperatures (all temperatures, low temperatures, or high temperatures), if any, the reaction is spontaneous.

a. 2 CO(g) + O(g) 2 CO(g) b. 2 NO(g) 2NO(g) + O(g) AH AH = -566.0 kJ = +113.1 kJ c. 2 H(g) + O(g) 2HO(g)
