In which cases entropy decreases?
In which cases entropy decreases? – In the polymerisation it is found that the number of molecules present is decreasing, the randomness decreases and hence, entropy also decreases. – Hence, we can say that the correct option is (d), that is in Polymerisation, entropy decreases.
