A reaction rate tells how fast products change into reactants.

False

A reaction that has a high activation energy is more likely to occur than a reaction with a low activation energy.

False

A reaction with a -△H is endothermic.

False

A thermodynamically favorable reaction proceed spontaneously.

False

Spontaneous reactions always occur rapidly.

False

The peak of an energy diagram indicates the fastest elementary step.

False

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

False

The reaction rate is independent of the number of effective collisions.

False

Thermodynamics can answer the question "How fast will it react?"

False

Thermodynamics can be described as a path-dependent study.

False

A decrease in temperature usually decreases the rate of a reaction.

True

All reactions with a -△G will proceed given the proper conditions of temperature and pressure.

True

Any factor that increases the number of effective collisions increases the reaction rate.

True

Energy is always required to break bonds within a molecule.

True

Even if △G is negative, a reaction might not occur rapidly.

True

Kinetics deals with the speed of reactions.

True

Kinetics deals with the steps of reactions.

True

The activated complex is a transition state in a reaction that lasts for only a few femtoseconds.

True

The collision theory explains why reaction rate depends on reaction conditions.

True

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

True
