Decide which of the following statements are true and which are false.
1. In order for two separate 1.0 L samples of O2(g) and
H2(g) to have the same average velocity, the
H2(g) sample must be at a higher temperature than the
O2(g) sample.
2. At constant temperature, the heavier the gas molecules, the
smaller the average kinetic energy.
3. As temperature decreases, the average kinetic energy of a sample
of gas molecules increases.
4. At constant temperature, the lighter the gas molecules, the
larger the average velocity.
5. Real gas molecules behave most ideally at low temperature and
high pressure.
6. Ideal gas molecules have small volumes and exert weak attractive
forces on one another.

Decide which of the following statements are True and which are
False about equilibrium systems:
True False For the following reaction:
H2(g) + F2(g) ⇌ 2HF(g) the
values of K and Kp are not the same.
True False A large value of K means the equilibrium
position lies far to the left.
True False For a reaction with K >> 1, the rate of
the forward reaction is greater than the rate of the reverse
reaction at equilibrium.
True False For the following reaction:...

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.

Decide which of the following statements are True and which are
False about equilibrium systems:
If K = 8 for the reaction A + B ⇌ C + D, K will equal -8 for the
reaction C + D ⇌ A + B

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.

Identify which of the following statements is true and which is
false.
1) _________ For a set of
numerical data, if the mean is larger than the median, this is
evidence of right-skew.
2) _________ Negative
values of the standard deviation indicate that the set of values is
even less dispersed than would be expected by chance alone.

true or false and explain why:
A) If Jane buys a brand new 2016 car in 2017, 2017 GDP does not
change.
B) The CPI is a better indicator of the price level than the GDP
deflator
C) If workers at a customer service call center in Durham, NC
