Collision Theory Recap

Front

What happens to the reaction rate when the container size of a gas is shrunk?

Back

The reaction rate will speed up.

Front

Define collision theory.

Back

Molecules must collide in the correct orientation with enough energy to bond.

Front

True or False: With an increase in temperature, the average kinetic energy of molecules increases, leading to a decrease in the number of collisions per unit time.

Back

False.

Front

What is the rate of reaction?

Back

The time it takes for a reaction to occur.

Front

Which has more surface area: Large chunks of chalk, Cube of sugar, Powdered sugar, or Small chunks of sugar?

Back

Powdered sugar.

Front

What is the effect of temperature on reaction rates?

Back

Increasing temperature generally increases reaction rates.

Front

What role does surface area play in reaction rates?

Back

Greater surface area allows for more collisions, increasing the reaction rate.

Front

What is activation energy?

Back

The minimum energy required for a reaction to occur.

Front

How does concentration affect reaction rates?

Back

Higher concentration increases the number of collisions, speeding up the reaction.

Front

What is the relationship between pressure and reaction rates in gases?

Back

Increasing pressure decreases the volume, leading to more collisions and a faster reaction rate.
