Solution: Rank the following compounds in order of increasing entropy at 25°C?A. MgCO3 (s)B. CO (g)C. Ni (s)D. H2O (I)E. CH3OH (I)

Problem

Rank the following compounds in order of increasing entropy at 25°C?
A. MgCO(s)
B. CO (g)
C. Ni (s)
D. H2O (I)
E. CH3OH (I)

Solution

We’re being asked to rank the given compounds in order of increasing entropy at 25 ˚C

The given compounds are: MgCO3(s), CO(g), Ni(s), H2O(l), CH3OH(l)


Recall that entropy is the degree of chaos or disorder of a system and that it depends on the following:
