Question

Give a clear handwritten answer with explanation 

Consider the reaction
Ca(OH)₂(aq) + 2HCl(aq)→→→→CaCl₂(s) + 2H₂O(1)
for which AH° = -30.20 kJ and AS° = 205.9 J/K at 298.15 K.
(1) Calculate the entropy change of the UNIVERSE when 1.760 moles of Ca(OH)₂(aq) react
under standard conditions at 298.15 K.
ASuniverse =
(2) Is this reaction reactant or product favored under standard conditions?
J/K
(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'.
