When disorderness of a system increases, the change is said to be:
Open in App
Solution
The correct option is D Spontaneous
As disorderness or randomness of a system increases entropy increases i.e. ΔS=+ve and the change will be spontaneous.
Theory:
Spontaneous process: A process which occurs in a certain direction on its own or by proper initiation.
Note: Does not necessarily take place instantaneously or at a fast rate. These processes are favorable and feasible.
Entropy is defined as a measure of randomness or disorder of a system.
All-natural processes are spontaneous because of an increase in randomness.
