We’re being asked to Predict which substance has greater molar entropy.
Recall that entropy is the degree of chaos or disorder of a system and that it depends on the following:
1. Phase: The gas phase has the highest entropy, followed by the liquid, and then the solid phase with the lowest entropy.
Gas > Liquid > Solid
2. Complexity: More elements in the compound leads to higher entropy.
Ex. NO3(g) [4 elements] has higher entropy than NO2(g) [3 elements].
3. Mass: The greater the mass, then the greater the entropy.
Ex. Xe(g) [greater mass] has higher entropy than He(g).
Predict which substance has greater molar entropy. Explain.
(a) P4(g) or P2(g)
(b) HNO3(aq) or HNO3(l)
(c) CuSO4(s) or CuSO4·5H2O(s)
