Rates of Reactions

Front

What is the effect of increasing the concentration of reactants on the rate of reaction?

Back

Increasing the concentration of reactants increases the rate of reaction.

Front

What is the minimum amount of energy needed for colliding particles to react called?

Back

Activation Energy.

Front

As the frequency of __________ increases, what happens to the rate of reaction?

Back

The rate of reaction increases.

Front

Which group of particles shows that increasing surface area increases collisions among particles?

Back

Right side.

Front

Why does a higher concentration increase the rate of reaction?

Back

It increases the frequency of particle collisions.

Front

Define 'Rate of Reaction'.

Back

The speed at which reactants are converted into products in a chemical reaction.

Front

What factors affect the rate of reaction?

Back

Concentration, temperature, surface area, and presence of catalysts.

Front

How does temperature affect the rate of reaction?

Back

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

Front

What is a catalyst?

Back

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

Front

Explain the concept of collision theory.

Back

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