Decide which of the following statements are true and which are false.

1. Real gas molecules behave most ideally at high temperature and low pressure.

2. At constant temperature, the heavier the gas molecules, the larger the average velocity.

3. Ideal gas molecules have small volumes and exert weak attractive forces on one another.

4. In order for two separate 1.0 L samples of O2(g) and H2(g) to have the same average velocity, the O2(g) sample must be at a lower temperature than the H2(g) sample.

5. As temperature increases, the average kinetic energy of a sample of gas molecules decreases.

6. At constant temperature, the heavier the gas molecules, the smaller the average kinetic energy.

Decide which of the following statements are true and which are false, concerning the kinetic molecular theory. 1. The particles are assumed to exert no forces on each other; they are assumed neither to attract nor to repel each other. 2. The molecules in a real gas have finite volumes and do exert forces on each other, thus real gases do not conform to some of the assumptions of an ideal gas as stated by the kinetic molecular theory. 3....

Decide which of the following statements are True and which are False about equilibrium systems: The value of K at constant temperature depends on the amounts of reactants and products that are mixed together initially. For a reaction with K >> 1, the rate of the forward reaction is less than the rate of the reverse reaction at equilibrium. A large value of K means the equilibrium position lies far to the left. For the following reaction: CaCO3(s) ⇌ CaO(s)...
