If a system is left to change spontaneously, in what state will it end?
a. the state with lowest possible energy and maximum disorder
b. the state with the maximum disorder and the highest energy
c. the same state in which it began
d. the state with the lowest possible energy consistent with the state of maximum disorder

 the state with the lowest possible energy consistent with the state of maximum disorder

Explanation:  Spontaneous means that the system does not require any external force to produce nay kind of energy or work.

Thus when a system is left to change spontaneously that is on its own accord, the state with the lowest possible energy consistent with the state of maximum disorder will result.

As lowest possible energy state is the most stable state and maximum disorder means the maximum entropy.

i had this on my unit activity, i can you if you are a plato student. are you a plato student?
