Reaction Rates

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

What is the effect of concentration on reaction rates?

Back

Higher concentration increases the frequency of particle collisions, leading to a faster reaction rate.

Front

What is the activated complex?

Back

A temporary, unstable arrangement of atoms that forms during a reaction at the peak of the energy barrier.

Front

How does surface area affect reaction rates?

Back

Increasing surface area allows more particles to collide, increasing the rate of reaction.

Front

What does the term 'exothermic reaction' mean?

Back

A reaction that releases energy, usually in the form of heat.

Front

What does the term 'endothermic reaction' mean?

Back

A reaction that absorbs energy from its surroundings.

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

What is a catalyst?

Back

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

Front

What is the role of a catalyst in a chemical reaction?

Back

It lowers the activation energy required for the reaction to occur.

Front

What is the difference between a reactant and a product?

Back

Reactants are substances that undergo a chemical change, while products are the substances formed as a result of the reaction.
