APFIVE Activation Energy and Thermodynamic Favorability
How does the concept of activation energy explain why some thermodynamically favorable reactions occur at an unmeasurable rate?
A
Activation energy has no effect on reaction rate; only thermodynamic favorability determines the speed of a reaction.
B
Thermodynamically favorable reactions always occur rapidly, regardless of activation energy.
C
Low activation energy slows down the reaction rate, making thermodynamically favorable reactions occur slowly.
D
High activation energy creates a kinetic barrier that prevents the reaction from proceeding at a measurable rate despite being thermodynamically favorable.
