Entropy is a state function since it depends not only on the start and end states, but also on the entropy change between two states, which is integrating tiny entropy change along a reversible route. Note: ... The universe's entropy is always rising. The change in total entropy is always positive.

How entropy is a state function in chemistry?

Entropy is defined as the degree of randomness or measure of disorder . ... Entropy is a State Function because it depends only on the initial and final thermodynamic states and not on the path followed.

Is entropy always a state function?

Entropy is surely a state function which only depends on your start and end states, and the change in entropy between two states is defined by integrating infinitesimal change in entropy along a reversible path.
