Question description

Ca(OH)2(aq) + 2HCl(aq)CaCl2(s) + 2H2O(l)

for which H° = -30.20 kJ and S° = 205.9 J/K at 298.15 K.

(1) Calculate the entropy change of the UNIVERSE when 1.581 moles ofCa(OH)2(aq) react under standard conditions at 298.15 K.
Suniverse =  J/K
(2) Is this reaction reactant or product favored under standard conditions?

(3) If the reaction is product favored, is it enthalpy favored, entropy favored, or favored by both enthalpy and entropy? If the reaction is reactant favored, choose'reactant favored'.
