<p>hey everybody..
i know i might sound stupid but i wanan ask all those chem wizards out there about the relation between entropy and stability?
are they directly proportional or inversely propotional
thanks...</p>
<p>bump! COME ON SOMEBODY HAS TO KNOW A BIT OF BASIC CHEMISTRY...</p>
<p>Bump!.. No.. Urgent Bump!!!</p>
<p>well PR says high entropy corresponds to more stability, however some other books says the exact opp thing..</p>
<p>as entropy increases, stability decreases, vice versa. therefore there is an inverse relationship between entropy and stability</p>
<p>it makes sense because entropy is the amount of order or disorder in a system. so, the more disorder (the more entropy, or more delta S) in the system, the less stable the system is. :-P hope that helped.</p>
<p>I disagree. If the thing has higher entropy it has lower energy from the gibbs equation
E = H - T*S
IF it has lower energy, its more stable (less likely to react)</p>
<p>Systems react to go towards higher entropy, which is energetically speaking downhill</p>
<p>okay.. thanks.. anybody else??</p>
<p>dG = dH - TdS</p>
<p>where dG is the change in Gibb's free energy.</p>
<p>The more positive the entropy change, the more negative dG is, hence the more favourable a given reaction is. Check wikipedia for a rough understanding.</p>
<p>in short... more the entropy more the stabiity right??</p>
<p>Yes, because the system wants to become more disordered, so it is more stable that way.</p>
