Chemistry in the Earth System IS4T3 Review: Collision Theory

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

What effect does increasing the temperature of a solution have on the rate of reaction?

Back

It speeds up the rate of reaction.

Front

Which has more surface area: large chunks of chalk, a cube of sugar, powdered sugar, or small chunks of sugar?

Back

Powdered sugar.

Front

What can be concluded if it took 6 minutes to reach the half-life at 200°C and 80 minutes at 50°C?

Back

Increasing temperature increases the rate of reaction.

Front

What is the relationship between surface area and reaction rate?

Back

Increased surface area leads to a faster reaction rate.

Front

How does concentration affect the rate of reaction?

Back

Higher concentration increases the rate of reaction.

Front

What role does energy play in collision theory?

Back

Molecules need enough energy to collide and react.

Front

What is the minimum energy required for a reaction to occur called?

Back

Activation energy.

Front

How does temperature influence the kinetic energy of molecules?

Back

Increasing temperature increases the kinetic energy of molecules.
