Final answer:
The speed of a process does not affect the spontaneity of a reaction. Spontaneity is determined by the change in the distribution of matter and/or energy.
Step-by-step explanation:
The speed of a process does not directly affect the spontaneity of a reaction in general. Spontaneity is determined by the change in the dispersal or distribution of matter and/or energy. A spontaneous process occurs when it results in a more uniform distribution of matter or energy, regardless of the speed of the process.
