Reaction Rates

Front

What is Activation Energy?

Back

The minimum energy required to initiate a chemical reaction.

Front

How does increasing the surface area of a reactant affect the rate of reaction?

Back

It increases the rate of reaction by allowing more collisions between reactant particles.

Front

What effect does decreasing particle size have on reaction rates?

Back

It increases reaction rates by increasing the number of collisions between particles.

Front

What is the role of Agitation/Stirring in chemical reactions?

Back

Agitation/Stirring increases reaction rates by causing more particles to collide.

Front

What is the energy required to break chemical bonds called?

Back

Activation Energy.

Front

What is the relationship between temperature and reaction rates?

Back

Increasing temperature generally increases reaction rates by providing more energy to the particles.

Front

How does concentration affect reaction rates?

Back

Increasing concentration increases the number of particles, leading to more collisions and a higher reaction rate.

Front

What is a catalyst?

Back

A substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the effect of pressure on gas reactions?

Back

Increasing pressure increases reaction rates by reducing the volume and increasing the frequency of collisions.

Front

What is an endothermic reaction?

Back

A reaction that absorbs energy from its surroundings, often in the form of heat.
