What is the relationship between concentration and reaction rate?

Direct relationship; as concentration increases, reaction rate increases.

What is the difference between exothermic and endothermic reactions?

Exothermic reactions release energy, while endothermic reactions absorb energy.

What is the relationship between temperature and reaction rate?

Direct relationship; as temperature increases, reaction rate increases.

How does a catalyst work?

A catalyst provides an alternate pathway for the reaction with a lower activation energy.

What does a catalyst do?

It speeds up the reaction.

What is the definition of activation energy?

The minimum amount of energy required for a reaction to occur.

How does entropy change between a gas and a liquid?

Gas has higher entropy compared to liquid.

What is the difference between a large and small surface area?

A larger surface area provides more exposed area for reactions.

How does surface area affect reaction rate?

Higher surface area leads to a higher reaction rate.

What are three factors that affect reaction rate?

Catalyst, pressure, temperature, surface area, concentration.

How does the energy of products differ between endothermic and exothermic reactions?

Endothermic products have higher energy, exothermic products have lower energy.

How does increasing pressure affect concentration?

Increasing pressure leads to an increase in concentration.

What are three parts of the collision theory?

Bimolecular collision, angle, orientation, and activation energy.

What are three types of equilibrium?

Chemical equilibrium, phase equilibrium, solution equilibrium.

What stress factors affect equilibrium?

Pressure, concentration, temperature.

Which direction is a forward reaction?

From left to right.

Define equilibrium.

State of balance.
