Chemistry Chapters 13 and 14 Review

Kinetics can be described as a path-dependent study.

• True

• False

Even if  $\Delta G$  is negative, the reaction might not occur spontaneously.

• True

• False

The collision theory states that particle collisions must occur before  a reaction takes place.

• True

• False

The collision theory explains why reaction occur at greater or slower rates, depending on reaction conditions.

• True

• False

The reaction complex is a theoretical, unstable, high-energy, transitional substance in a reaction.

• True

• False

The lower the activation energy, the faster the reaction will occur because the activation energy is the minimum amount of kinetic energy that must be possessed by the colliding molecules before they can react.

• True

• False

What is the study of the rates of reactions and the steps by which they occur?

• Kinetics

• Potentials

• Reflexology

What is a substance that changes a reaction rate without being permanently changed or consumed by the reaction?

• product

• reactant

• catalyst

• precipitate

What is a common pain reliever that functions by inhibiting the action of two different enzymes that lead to inflammation and pain?

• peppermint oil

• aspirin

• ibuprofen

• ethanol

What type of steps are often what reaction mechanisms are made of?

• mechanism

• Elementary

• intermediate

• complex
