Twin: Spontaneous Does Not Mean Fast
Captions available
The idea
A spontaneous process can proceed at any rate, since spontaneity names direction while rate is a separate kinetic question, Unit 9's domain.
In practice
Diamond's conversion to graphite is spontaneous at room pressure, yet too slow to observe in a human lifetime.
Where people slip
Calling a slow spontaneous process "not really happening" confuses thermodynamics with kinetics.
