Surface area of reactants example
WebSep 16, 2024 · Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur. You can see an example of this in everyday life if you have ever tried to start a fire in the … WebExample Unit of Concentration The increase within the concentration of reactants is reflected in the speed of reaction as it will increase. Ions and molecules will react to create a brand new compound by increasing the amount of reactants. As the concentration of reactants decreases, fewer and fewer molecules and ions are present.
