Question

2. Decide whether each of the following statements is true or false. If false, rewrite it to make it true. a. Entropy of the universe increases in all spontaneous reactions. wo False If entropy is bw enough it con be spontaneous, b. Reactions with a negative free energy change (A-Gº <0) are product-favored and occur with rapid transformation of reactants to products. True c. An exothermic reaction will always be spontaneous. I NO when AH is negative the reaction can be spontaneous at a certain tem d. Endothermic processes are never spontaneous. e. The entropy of a substance increases on going from liquid to the vapor state at any temperature True f. Reactions with a positive A Itº and a positive AS can never be product favored. false at high temperatures its g. If 4 Gº for a reaction is negative, the reaction will have an equilibrium constant greater than 1.

Answer 1

(2) According to 2nd law of thermodynanies entropy always increases for spontaneous procent. Troues b) where sheron zo negative (always spontaneous) hence product favoured Torce ☺) DGC Nou = 104401 – | TOSO . For exothere process IDAO =-ve but if no any eare 080 =-100901 (entropy deerears), then German = 1 101 +TAM! if Togo Lohol then inspite of the fact Dho =-ve, Abe the (non-spontaneous) false of For endother process B40 = +1000 If 09 = t1osol and Togol > Aho from equation 2 sbéron co (spontaneous) . false e Order of entropy gas > Liquid> Solid True (6) If I TASOI > DAOI then Geco and hence it can be product favourelle fale O DGC - RT enkea - AGO <0 then keq> 1 True.
