What is the unit of entropy change?

"The entropy of solids increases on melting". Do you agree with the statement? Justify.

Why does the entropy of a solid increase on fusion?

What is meant by entropy driven reaction?

Justify the following statements: b. The entropy of a substance increases on going from liquid to vapour state at any temperature:

The standard emf of the cell reaction Zn _((s)) + Cu _(aq) ^(2+) to Zn _(aq) ^(2+) + Cu _((s)) 1.1 V. If standard enthalpy change of the reaction is -216.7 kJ, what is standard entropy change of the reaction in JK^(-1)mol^(-1) ?
