The entropy of the system increases or decreases for the given process has to be predicted. Concept Introduction: The randomness present in the system is called its entropy. It is an extensive property. At equilibrium, the entropy of the system is zero. The entropy that is measured under the standard conditions of temperature is known as standard entropy. The entropy for one mole of the substance under standard conditions is called standard molar entropy.

A chemical reaction occurs inside the system for which ΔrU = 11.38 KJ. (A) What is the change in entropy for the surroundings for the process, ΔSsurr? (B) What are the ranges of possible values for the change in entropy of the system, ΔSsys , for this process?

A critical reaction in the production of energy to do work or drive chemical reactions in biological systems is the hydrolysis of adenosine triphosphate, ATP, to adenosine diphosphate, ADP, as described by the reaction ATP(aq) + H,O(1) → ADP(aq) + HPO (aq) for which AGxn = –30.5 kJ/mol at 37.0 °C and pH 7.0. Calculate the value of AGrn in a biological cell in which [ATP] = 5.0 mM, [ADP] = 0.30 mM, and [HPO,] = 5.0 mM.
