PPT-The Third Law, Absolute Entropy and Free Energy

Lecture 4 The Third Law If the entropy of each element in some crystalline state may be taken as zero at the absolute zero of temperature every substance has a finite positive entropy but at absolute zero the entropy may become zero and does so become in the case of perfectly crystalline substances. Energy. Entropy. Free Energy. What is Force ?. F. =. m. a. force. mass. accel. .. What is Force ?. S . F. =. m. a. “Sum of the forces on an object is (directions matter) is equal to the mass of that object multiplied by it’s acceleration”. 6.04. What does ‘Spontaneous’ Mean in Chemistry?. A spontaneous change is a change in a system that proceeds without a net input of energy from an outside source.. Needs some activation energy to get started. MEANING OF THE TERM? . CLUE.

Tds relations relate properties of any pure substance exactly to entropy change. But it is not convenient to use them.. Instead tabulated data for . s. are used, e.g.. Table B.1. for water..

Because . entropy is a state function, . the property is what it is regardless of pathway, the . entropy change for a given reaction can be calculated by taking the difference between the . standard entropy.
