Give me atleast 10 example of Non spontaneous process​

Sagot :

Gtalitegamesidn

Explanation:

Examples for non-spontaneous reactions are: Diffusion of gas from low pressure to a high pressure. Flow of heat from cold body to a hot body. Where, ΔG is Gibbs free energy ΔH is the change in enthalpy and ΔS is the change in entropy.

10 EXAMPLES OF NON SPONTANEOUS PROCESS

____________________

What is non-spontaneous process?

- A non-spontaneous processes does not takes place on its own. It needs continuous external influence. Once started, a non-spontaneous processes will stop, when the continuous external force is withdrawn. For non-spontaneous processes, the change in Gibbs free energy is positive (ΔG>0).

Examples of non-spontaneous processes:

1.) Flow of heat from inside of refrigerator to the room. Room is at higher temperature than refrigerator.

2.) Boiling of water.

3.) Flow of heat from cold body to a hot body.

4.) Diffusion of gas from low pressure to a high pressure.

5.) A ball rolling uphill.

6.) Ice melting at- 10 degree's celcious.

7.) A smell diffusing in a room.

8.) Ice melting in lukewarm water.

9.) Dissolution of sand in water.

10.) Compression of gas.
