Activation Energy and Thermodynamic Favorability
Which statement best explains why a thermodynamically favorable reaction may proceed at an unmeasurably slow rate?
A
Thermodynamically favorable reactions always occur rapidly, regardless of activation energy.
B
High activation energy creates a kinetic barrier that prevents the reaction from proceeding at a measurable rate despite being thermodynamically favorable.
C
Activation energy has no effect on reaction rate; only thermodynamic favorability determines the speed of a reaction.
D
Low activation energy slows down the reaction rate, making thermodynamically favorable reactions occur slowly.
