Consider the reaction: KCIO4(s) →KCI(s) + 202(g) and the table of values given on the right. Do you expect this reaction to be spontaneous at room temperature? Why? (A) Yes, because AGrxn is negative. (B) Yes, because Hrxn is negative. (C) Yes, because AHrxn is positive. (D) No, because AGrxn is positive. (E) No, because Hrxn is positive. Substance AG fº (kJ/mol) KCIO4(s) -300.4 KCI(s) -408.2 02(8) 0 ΔΗ,° (kJ/mol) -433 -437 0
