Title: Why do smaller particles have large surface area and equilibrium
Post by: sameeralord on June 30, 2008, 11:14:19 PM

Hello guys,

This might be a simple concept for you guys but I'm bit confused. We are learning rates of reaction and why does a crushed tablet react quicker than a full tablet. Any diagrams to help me with this would also be great.

And while we are at I got few questions on equilibirum constant.

Let's say we have to write our own equation and let's say its a combustion reaction. We can choose if the product water is liquid or gas. But If choose liquid I won't be able to use it in the equillibirum constant K (we haven't learned the gas one. the normal one I mean). So which state do I use

Why is temperature the only thing that changes th equilibirum constant?

Any help in any of these questions would be greatly appreciated  ;).Thank you!!

Increased surface area from the crushed tablet provides more sites for a reaction to take place.
