Question 1

The standard molar free energies of formation of NO2(g) and N2O4(g) at 25°C are 51.840 and 98.09 kJ/mol, respectively. What is the value of Kp (in atm) for the reaction written as follows at 25°C?
    2NO2 N2O4

◦ 4.79 × 1011

◦ 1.00
◦ 9.55
◦ 4.28 × 10–36

◦ 7.81 × 10–9


Question 2

◦ 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.
