WebSep 1, 2024 · Three ways to increase the rate of a chemical reaction is by changing factors, such as concentration, temperature, and surface area. The equal mass of sugar crystals has a greater surface area than the sugar cube. This is because more of the particles are exposed, so the reaction will happen faster. arti narasumber https://pdafmv.com

Effect of surface area on rate - Factors that affect the rate …

WebApr 11, 2024 · A higher concentration increases the number of molecules available for collision. This increases the rate of collision and hence the rate of reaction. 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. WebThe rate of a surface-catalyzed reaction increases with the surface area of catalyst in contact with the reactants. Therefore, the solid support inside of a catalytic converter is designed to have a very high surface area, hence … WebFeb 17, 2016 · For solid reagents, we can increase their surface area. Using a reagent in a big, solid lump means that only the particles at the surface are exposed and available for reaction initially. By dividing the lump into smaller, finer pieces, we increase the number of particles available for reaction. This increases the frequency of collisions, and ... arti narapidana
