Question

write the Key points of spontaneous process​

Answer 1

Answer:

Key points of spontaneous process

i. It occurs of its own and does not require any external agency to occur.

ii. It proceeds in one direction and cannot take place in the opposite direction unless the external stimulant is present.

iii. The spontaneous processes can be rapid or slow or spontaneity is not concerned with the rate of the reaction.

iv. The processes continues till equilibrium is reached. The spontaneous (natural) processes tend to occur in a direction that leads to equilibrium

Answer 2

Answer:

Some key points of spontaneous process are as follows :

• 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.

• A spontaneous process is capable of proceeding in a given direction without needing to be driven by an outside source of energy.

• For cases involving an isolated system where no energy is exchanged with the surroundings, spontaneous processes are characterized by an increase in entropy.

• The laws of thermodynamics govern the direction of a spontaneous process, ensuring that if a sufficiently large number of individual interactions are involved, then the direction will always be in the direction of increased entropy.
