Chemical Kinetics

Front

What factors increase the rate of a reaction?

Back

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

Front

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

Back

It increases both the frequency and energy of particle collisions.

Front

The rate of a reaction increases as temperature __________.

Back

Increases.

Front

What effect does adding a catalyst have on the activation energy of a reaction?

Back

It causes a decrease in the activation energy.

Front

What is required for a collision between two reactant particles to be effective?

Back

Sufficient kinetic energy.

Front

Define chemical kinetics.

Back

The study of the rates of chemical reactions and the factors affecting them.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

How does concentration affect reaction rate?

Back

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

Front

What role does surface area play in reaction rates?

Back

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

Front

What is the effect of temperature on the kinetic energy of particles?

Back

Higher temperature increases the kinetic energy of particles.
