In which of the following processes does the molecules become more orderly?

Which of the following processes shows a decrease in entropy of the system?

Consider the following reaction at constant P.  Use the information here to determine the value of ΔSsurr at 298 K (In J/K).  Predict whether or not this reaction will be spontaneous at this temperature. (EX: 100, spontaneous)

            N₂(g) + 2 O₂(g) → 2 NO₂(g)            ΔH = +66.4 kJ 

Consider a reaction that has a negative ΔH and a positive ΔS.  Which of the following statements is TRUE?

For the following example, identify the following.

            H₂O (l)  → H₂O(g)

Above what temperature (in K) does the following reaction become nonspontaneous?

2 H₂S(g) + 3O₂(g)  → 2SO₂(g) + 2H₂O(g)           ΔH =  -1036 kJ;  ΔS =  -153.2 J/K

Identify the statement that is FALSE.

Place the following in order of increasing entropy at 298 K.

            Ne       Xe       He       Ar        Kr
