Qualitative guidelines for entropy Which of the following are true statements? a) For the reaction CO2(g) CO2(s) entropy increases b) For the reaction NaCl(s) + H2O(l) NaCl(aq) entropy increases c) Molecules of Cl2(g) should have have greaterentropy per mole than molecules of SO2(g) d) If entropy decreases for a certain spontaneous process, theentropy of the universe increases Qualitative guidelines for entropy Which of the following are true statements? a) For the reaction CO2(g) CO2(s) entropy increases b) For the reaction NaCl(s) + H2O(l) NaCl(aq) entropy increases c) Molecules of Cl2(g) should have have greaterentropy per mole than molecules of SO2(g) d) If entropy decreases for a certain spontaneous process, theentropy of the universe increases
Explanation / Answer
statements b , d aretrue & a,c are false statement a is falsebecause gases has more entropy than solids thereforeinthis reaction entropy decreases . statement b is true because liquidhas more entropy than solid of a substance statement c is falsebecause due to greater number of degrees of freedom SO2(g) willhave more entropy than Cl2 gas . statement d is true because all spontaniousprocesses produce an increase in entropy .
