Question
Place the following in order of decreasing standard molar entropy. NaCl(s) Na_3PO_4(aq) NaCl(aq) NaCl(s) > Na_3PO_4(aq) > NaCl(aq) NaCl(s) > NaCl(aq) > Na_3 PO_4(aq) Na_3PO_4 (aq) > NaCl(aq) > NaCl(s) NaCl(aq) > Na_3PO_4(aq) > NaCl(s) NaCl(aq) > NaCl(s) > Na_3PO_4 (aq) What is true if ln K_eq is negative? Delta G degree_rxn is positive and the reaction is spontaneous in the reverse direction. Delta G degree_rxn is zero and the reaction is at equilibrium. Delta G degree_rxn is positive and the reaction is spontaneous in the forward direction. Delta G degree_rxn is negative and the reaction is spontaneous in the forward direction. Delta G degree_rxn is negative and the reaction is spontaneous in the reverse direction. What is the definition of entropy? A thermodynamic property of a substance proportional to its internal energy. A thermodynamic property of substances proportional to the degree of order. A thermodynamic property of a substance proportional to spontExplanation / Answer
Place the following in order of decreasing standard molar entropy. NaCl(s) Na3PO4 (aq) NaCl(aq), C) Na3PO4 (aq) > NaCl (aq) > NaCl(s).
Answer C) Na3PO4 (aq) > NaCl (aq) > NaCl(s)

========================================= Entropy
Compound and physical changes in a framework might be joined by either an expansion or a reduction in the turmoil of the framework, comparing to an expansion in entropy (S > 0) or a diminishing in entropy (S < 0), individually. Similarly as with some other state work, the adjustment in entropy is characterized as the distinction between the entropies of the last and introductory states: S = Sf Si.
At the point when a gas ventures into a vacuum, its entropy increments on the grounds that the expanded volume takes into consideration more noteworthy nuclear or atomic issue. The more prominent the quantity of particles or atoms in the gas, the more noteworthy the confusion. The size of the entropy of a framework relies on upon the quantity of minute states, or microstates, connected with it (for this situation, the quantity of iotas or atoms); that is, the more noteworthy the quantity of microstates, the more noteworthy the entropy.
