WebExplain, in terms of collisions, why increasing the surface area of the hot carbon increases the rate of the forward reaction. [1] Increasing surface area will have more collisions A chemical reaction occurs when reactant particles Collide with proper energy and proper orientation Systems in nature tend to undergo changes toward Websurface area. Smaller droplets react more quickly than do large ones, increasing the acceleration of the escaping gases. A LIST OF KEY CONCEPTS The rate of a chemical reaction is the speed with which reactants are converted to products. Collision Theory is used to explain why chemical reactions occur at different rates. WebMar 26, 2016 · Some reactants aren't completely dissolved but come in larger, undissolved particles. In these cases, smaller particles lead to faster reactions. Smaller particles expose more surface area, making a greater portion of the particle available for reaction. Catalysts increase reaction rates. اسم دختر با آ
