For a reaction,
4M(s) + nO₂(g) → 2M₂Oₙ(s),
the free energy change is plotted as a function of temperature. The temperature below which the oxide is stable could be inferred from the plot as the point at which

Upvote For one mole of an ideal gas, which of these statements must be true?
(a) U and H each depends only on temperature

(a) U and H each depends only on temperature
(b) Compressibility factor z is not equal to 1
(c) Cp,m – Cv,m = R
(d) dU = CvdT for any process
U and H are temperature dependent
Cp, m – Cv, m = R (for 1 mole of ideal gas)
dU = CvdT
