Question

state the difference between spontaneous and non spontaneous .​

Answer 1

Answer:

A spontaneous process is capable of proceeding in a given direction without needing to be driven by an outside source of energy. ... An endergonic reaction (also called a nonspontaneous reaction) is a chemical reaction in which the standard change in free energy is positive and energy is absorbed

Answer 2

Answer:

A spontaneous process is the time-evolution of a system in which it releases free energy and it moves to a lower, more thermodynamically stable energy state. For cases involving an isolated system where no energy is exchanged with the surroundings, spontaneous processes are characterized by an increase in entropy. Whereas a non spontaneous reaction needs an external energy to pump the reaction this direction. For example, without an external energy source, water will remain water forever.
