Chemical Equilibrium & Kinetics

Front

Define concentration in terms of chemical reactions.

Back

The amount of a substance in a given volume.

Front

What is a nonspontaneous reaction?

Back

A nonspontaneous reaction is a reaction that does not favor the formation of products at the specified conditions.

Front

Explain Le Chatelier's Principle.

Back

If a stress is applied to a system in dynamic equilibrium, the system changes in a way that relieves the stress.

Front

What is an inhibitor?

Back

A substance that interferes with the action of a catalyst; can slow down or stop a chemical reaction.

Front

What is dynamic equilibrium?

Back

Dynamic equilibrium is a state of balance between continuing processes.

Front

What factors affect the rate of a chemical reaction?

Back

Concentration, temperature, surface area, and the presence of catalysts or inhibitors.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst speeds up a chemical reaction without being consumed in the process.

Front

Describe the concept of equilibrium constant (K).

Back

The equilibrium constant (K) is a numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium.

Front

What is the difference between static and dynamic equilibrium?

Back

Static equilibrium involves no movement, while dynamic equilibrium involves ongoing processes that balance each other.

Front

How does temperature affect chemical equilibrium?

Back

Changing the temperature can shift the position of equilibrium, favoring either the forward or reverse reaction depending on whether the reaction is exothermic or endothermic.
