Share:
- 1A is for solid and C is for liquid form of an organic substance; Sm(A) = -(∂μA / ∂T)p✓
- 2A and B are for ice; Sm(B) = -(∂μB / ∂T)p
- 3A and B are for an organic liquid; Vm(B) = -(∂μB / ∂T)p
- 4A is for ice and C is for liquid water; Sm(C) = (∂μC / ∂p)T
Correct answer
A is for solid and C is for liquid form of an organic substance; Sm(A) = -(∂μA / ∂T)p
