Chemical Kinetics

What is the relationship between rate of reaction and temperature?

• No relationship

• Directly proportional

• Inversely proportional

• Jointly proportional

• The rate increases

• The rate decreases

• The rate will remain the same

• It has no effect

What is the relationship between rate of reaction and concentration of reactants?

• No relationship

• Directly proportional

• Inversely proportional

• Jointly proportional

How does the presence of catalyst increase reaction rate?

• It lowers down activation energy

• It increases collision of particles

• It increases the energy of the reactant

• It increases activation energy

• Rate of reaction

• constant, k

• rate law

• reaction order

The following are the terms used to describe the relationship between the rate of a chemical reaction and the concentration of its reactants EXCEPT
