alleryStart learning →A process spontaneous in one direction under given conditions is, in reverse:
ANonspontaneous
BAlso spontaneous
CAt equilibrium
DReversible only
Answer & Solution
Correct answer: A. Nonspontaneous
1. Spontaneity has a direction attached to it.
2. A process may be spontaneous in one direction under a particular set of conditions.
3. That same process is nonspontaneous in the reverse direction.
4. Only at equilibrium does neither direction dominate.
