Chemistry Ch.14 Study Guide True/False
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.
