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( normal one not the gas one). 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!!

because in the case of a crushed tablet you have all the surface area of each of the bits where as stuck together you only have a sufface area of the outside of the tablet.

Its like asking why a sponge has a greater surface area than a block of wood does
