Chemical Kinetics and Electric Circuits

Front

The study of the reaction mechanism and rates of chemical reactions.

Back

What is chemical kinetics?

Front

Who developed the Law of Mass Action?

Back

Peter Waage and Cato Maximillian Guldberg in 1864.

Front

The speed of a chemical reaction is proportional to the quantity of the reacting substances.

Back

What does the Law of Mass Action state?

Front

Characterized by the breaking of old bonds and formation of new bonds.

Back

What is a reaction mechanism?

Front

A temporary stage characterized by breaking of old bonds and formation of new bonds.

Back

What is an activated complex?

Front

What factors affect the rates of chemical reactions?

Back

1. Concentration of reacting substances 2. Pressure 3. Temperature

Front

Gas-phase chemical reactions occur when molecules collide with sufficient kinetic energy.

Back

What does Collision Theory explain?

Front

A substance that increases/decreases the rate of a chemical reaction without undergoing a permanent chemical change.

Back

What is a catalyst?

Front

A substance that increases the rate of a chemical reaction by decreasing the activation energy.

Back

What is a promoter or positive catalyst?

Front

A substance that decreases the rate of a chemical reaction by increasing the activation energy.

Back

What is an inhibitor or negative catalyst?
