Surface area of the reactant.
When size of cell increases ,its surface to volume ratio decreases , control of cell activities become difficult , contact area with surrounding decreases .
You can increase surface area by spreading the object
ALL reactions (apart from Nuclear) take place on the surface. By crushing the solid you are increasing the surface area and also the SA/Volume ratio. This increased surface area increases the area available for the dissolution reaction.
Through temperature, concentration, surface area, and the use of catalists. Temperature - most reaction go faster with a higher temperature (not always the case) So you raise or lower the temperature to control the speed. Concentration - this can be calculated. The higher the concentration the faster the outcome and the more product you get. Catalists will always make it faster. More catalist, fater reaction. Surface Area-The more surface area, the faster the reaction. for example, if you break up an antacid tablet (alka seltzer) it will dissolve faster than a whole one because it has more surface area

It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
The total surface area! The total surface area! The total surface area! The total surface area!
When size of cell increases ,its surface to volume ratio decreases , control of cell activities become difficult , contact area with surrounding decreases .
It should be relatively easy to find the surface area of a box when you are given the surface area.

It depends on the surface area of what!
