N₂O₄

◦ 4.79 × 10¹¹

◦ 1.00
◦ 9.55
◦ 4.28 × 10^–36

◦ 7.81 × 10^–9

Question 2

The third law of thermodynamics states:

◦ The entropy of the universe is increasing.
◦ The entropy of the universe is constant.
◦ The entropy is zero at 0 K for a perfect crystal.
◦ The absolute entropy of a substance decreases with increasing temperature.
◦ The entropy of the universe equals the sum of the entropy of system and surroundings.
