Reaction Rates

Front

Catalysts permit reactions to proceed along a ___________ energy path.

Back

lower

Front

Which factors increase the rate of a reaction?

Back

increasing temperature, increasing concentration, increasing surface area, all of these

Front

________ is the measure of how much area of an object is exposed.

Back

Surface Area

Front

What is the rate of reaction?

Back

How fast a reaction is

Front

Why does a higher temperature increase the rate of a reaction?

Back

it increases both the frequency and energy of particle collisions

Front

What is a catalyst?

Back

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

Front

What effect does increasing concentration have on reaction rates?

Back

It increases the number of reactant particles, leading to more collisions.

Front

How does surface area affect reaction rates?

Back

A larger surface area allows more particles to collide, increasing the reaction rate.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

How does temperature affect particle movement?

Back

Higher temperatures increase the kinetic energy of particles, causing them to move faster.
