Intermolecular Forces and Properties
At low temperatures, gas particles move slower and spend more time around each other. Which assumption of the Kinetic Molecular Theory does this violate?
All gases have the same average kinetic energy at a given temperature.
Gas particles move in random, constant, straight-line motion.
There are no attractive or repulsive forces between gas particles.
Collisions are elastic: when gas particles collide, no energy is lost.
In which industrial process is understanding the deviation from ideal gas behavior essential for safety and efficiency?
Electrolysis of water to produce hydrogen and oxygen gases.
Refrigeration using phase changes of freon gases.
High-pressure storage of natural gas.
Combustion reactions for power generation in engines.
What would likely cause a real gas to deviate from ideal behavior?
Small molecular size
Low intermolecular forces
High pressure
Low temperature
Which of the following gases would most likely deviate from ideal behavior under conditions of high pressure?
O2 because of its small molecular size.
NH3 due to strong hydrogen bonding.
Ne since it is a noble gas with weak intermolecular forces.
He due to its monoatomic and nonpolar nature.
Which factor can cause a real gas to deviate from ideal behavior?
Constant temperature conditions.
High pressure conditions.
Low reaction rates among molecules.
Perfectly elastic collisions between molecules.
What research question would most effectively isolate and analyze the role of molecular size in deviations from ideal gas law during compression?
How does Boyle's Law apply to real gases under varying temperatures while keeping pressure constant?
How do deviations from ideal gas law vary with molecular size when compressing different real gases to high pressures at consistent temperatures?
Does changing the partial pressures of components in a gaseous mixture affect Dalton’s Law predictions at standard laboratory conditions?
In what way does Avogadro’s hypothesis hold true for real gases when comparing equal volumes under identical conditions of temperature and pressure?
Which factor explains why H₂O vapor does not follow the ideal gas law closely at room temperature?
Strong dipole-dipole attraction among H₂O molecules
Reduction in overall momentum transfer during collisions
Increase in molecular speed for individual H₂O vapors
Diminished electron cloud distortion upon particle impact

How would we represent Graham's law of effusion mathematically? (Rate 1 represents the rate of effusion of the first gas, Rate 2 rate of effusion of the second gas; M1 represents the molar mass of the first gas, M2 molar mass of second gas)
(Rate 1 / Rate 2) = √(M2/M1)
(Rate 1 / Rate 2) = (M2/M1)²
(Rate 1 / Rate 2) = (M1/M2)²
(Rate 1 / Rate 2) = √(M1/M2)
What does the Van der Waals equation look like?
PV = nRT
