Did you know?
WebBy decreasing the particle size of a reactant, we are increasing its surface area. The greater the surface area, the higher the chance of collisions, thus the faster the rate of... WebApr 11, 2024 · Reducing the concentration, therefore, reduces the reaction rate. Increasing the surface area for reaction increases the reaction rate by providing a broad surface for a collision of molecules. We can achieve this by using smaller particles of solid reactants such as powder forms.
