Surface area increase reaction rate
WebThe reaction rate of a heterogeneous reaction depends on the surface area of the more condensed phase. Automobile engines use surface area effects to increase reaction rates. Gasoline is injected into each cylinder, where it … 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.
