9. What do you about the spontaneity of the following reactions? Remember that ΔG = ΔH − TΔS. The first one is solved as an examplea. If Δh for a reaction is negative and Δs is positive? if ΔH < 0 and ΔS > 0 then ΔG < 0 and the reaction is spontaneous.b. What if Δh is negative and Δs is negative?c. What if Δh is positive and Δs is negative? d. What if Δh is positive and Δs is positive? 9. What do you about the spontaneity of the following reactions? Remember that AG =AH-TAS. The first one is solved as an examplea. If Ah for a reaction is negative and As is positive? if AH < 0 and AS > 0 then AG < 0and the reaction is spontaneous.b. What if Ah is negative and As is negative?c. What if Ah is positive and As is negative?d. What if Ah is positive and As is positive?
