not to sound like a jerk but i cant tell if you meant surface and spelled it wrong and also the pls...i cant tell about it either

It changes the speed greatly.

Best way to tell it is this: Take two solid powders and mix it, well nothing, cause the molecules or atoms only touch each other and the very edge of the crystals, now if you make a solution then pour it together, voila de reaction is even better, same happens when you melt them, the best way though is in gas form. The free molecules, can touch each other at a free surface, they are not connected to other molecules in any way, so it's much easire for them to fly into each other.

There is an eqotation, that reaction speed equals the koncentration of the participants multiplied by k. This k is different in every reaction, and this includes the surface, temperature, pressure, and etc. So the surface is a part of the reaction speed.
