Entropy

What is Entropy and symbol

Measurement of disorder

Symbol ( S )

how does temp affect entropy

increase temp , increase disorder and increase entropy

order of entropy for states

gas>liquid>solid

what has biggger entropy , liquid ot gas or solid to liquid

liquid to gas

what has bigger entropy and why

S₈ . 4S_{2 .} 8S

4S > 4S₂ > S₈

increase freedom of movement , increase disorder m increase entropy

if # products > # reactants then

entropy change = positive

features of entropy graphs

-All show upward trend

2 large jumps -1 melting -2 boiling boiling>melting

start at origin -the entropy of all substances at 0K is 0

Standard molar entropy and units

entropy of 1 mole of substance at 298K

JK^-1mol^-1

equation of standard molar entropy
