How Does Surface Area Affect The Reaction Rate
Chemical reactions can happen slowly or fast. The speed of the reaction rate can be changed.
Some of the factors that can affect the reaction rate are surface area, temperature, and concentration and pressure.
Surface area is the exposed, outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example, if you place a donut stick into water, the donut will react slowly with the acid. This is because the acid only comes in contact with the particles on the surface of the donut. But, if you crush the donut first, more of the particles come in contact with the acid, and the reactions occurs faster.
Imagine sitting in
a gym, everyone running and playing basketball. It gets hot and humid. This is because at higher temperatures, the average speed of particles is greater. Particles collide more often, and collisions with more energy are more likely to break chemical bonds. For example, bread dough will rise more quickly in a warm place than in a cool one.
Increasing the concentration of one or more reactants increases collisions between particles. More collisions result in a faster reaction rate. Increasing the pressure on a reaction involving reacting gases increases the rate of reaction. For example, in an empty hallway, there will be a lower concentration level. But, once that hallway begins to fill, the concentration level becomes higher.
Surface area, temperature, and concentration and pressure are some of the factors that can affect the reaction rate. Without these things, the forward or reverse of the reaction rates could be altered.
