Reaction Rates

Front

What is Activation Energy?

Back

The minimum energy required to break bonds in reactants to initiate a chemical reaction.

Front

What is an Endothermic Reaction?

Back

A process that absorbs energy from its surroundings, resulting in a decrease in temperature and storing more energy than it releases.

Front

What is Exothermic Energy?

Back

The energy released when new bonds are formed during 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 happens to the reaction rate when more reactants are added?

Back

The reaction rate will speed up due to an increase in the number of collisions between reactant particles.

Front

Define a Catalyst.

Back

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

Front

What is the role of temperature in reaction rates?

Back

Increasing temperature generally increases reaction rates by providing more energy to the reactant particles, leading to more frequent and effective collisions.

Front

What is a Chemical Reaction?

Back

A process in which reactants are transformed into products through the breaking and forming of chemical bonds.

Front

What is the Collision Theory?

Back

A theory that states that for a reaction to occur, reactant particles must collide with sufficient energy and proper orientation.

Front

What is Concentration in the context of reaction rates?

Back

The amount of a substance in a given volume; increasing concentration typically increases the rate of reaction.
