Problem

Which one of the following reactions is likely to have a ΔS° close to zero (in other words, neither positive nor negative)?

a) PCl 3(g) + Cl2(g) ⇌ PCl 3(g)

b) 2KClO 3(s) ⇌ 2KCl(s) + 3O 2(g)

c) CO(g) + H 2O(g) ⇌ CO 2(g) + H 2(g)

d) CO 2(g) ⇌ CO 2(s)

e) C 512(l) + 8O 2(g) ⇌ 5CO 2(g) + 6H 2O(g)

 

 

Place the following compounds in order of increasing S°:

PCl5(s)          PCl 5(g)          PCl 3(g)

a) PCl5(s) < PCl5(g) < PCl3(g)

b) PCl5(s) < PCl3(g) < PCl5(g)

c) PCl5(g) < PCl5(s) < PCl3(g)

d) PCl5(g) < PCl3(g) < PCl5(s)

e) PCl3(g) < PCl5(g) < PCl5(s)

f) PCl3(g) < PCl5(s) < PCl5(g)
