Question 1
Predict whether Δ
S is positive or negative for the following process:
H
2O(g) → H
2O(s)
◦ negative
◦ positive
◦ Δ
S doesn't change.
◦ There is not enough information to determine.
Question 2
The change in Gibbs energy for a reaction:
◦ = Δ
H -
TΔ
S ◦ =
q (heat)
◦ = Δ
S +
TΔ
H ◦ = Δ
S -
TΔ
H ◦ = Δ
