I am looking for the connection between the two statements of 2nd law of thermodynamics
"Any physical or chemical process (change) is responsible for a net increase in the total chaos/disorder or its measure that is entropy of the universe." OR
"enthalpy change is a state function and thus independent of the path followed ie the heat evolved or absorbed during a chemical reaction at constant pressure is always the same whether the reaction takes place in one or several steps."(this is the statement of hess's law of constant heat summation put forward by
Hess in 1840 and is a part of our thermochemistry chapter at high school level)

Ill be obliged for a brief and straight forward explanation of this connection. mathematics is allowed.
