2 cards from this section. Quick, good the night before a test.
Define collision frequency in your own words.
Think about how often the molecules would bump into each other.
What does collision cross-section refer to?
Consider it as the 'target' area during a reaction.
What is the definition of collision frequency?
Think about how often molecules actually hit one another.
True or False: A larger collision cross-section leads to a higher probability of collisions occurring.
Consider the 'target' idea.
Calculate the collision frequency for two gases A and B with densities of 0.5 mol/L and 0.3 mol/L and a collision cross-section of 1.0 × 10^-10 m² at room temperature (298 K). Use the provided formula.
Remember to calculate the reduced mass before using the equation.
Explore how changing the concentration of gas A from 0.5 mol/L to 1.0 mol/L affects collision frequency without changing gas B concentration.
Revisit the basic principle of collision frequency in terms of concentration change.
