The rate of reaction involved in a chemical weathering is under the control wide range of capacity and intensity factors, acting as function of integration of capacity, intensity, and time. The weathering time can give rise to stage or degree of weathering. The various driving force affecting the rate of reaction involved in chemical weathering can be recognized to a extent of consideration for formation of soil are five usual factors including, time, parent material, relief, biotic forces, and climate. The conditions affecting the reaction rate of chemical weathering needs to be analyze more specifically in categories other than above listed five factors for formation of soil. Leaching effect is included in single intensity factor whether it is under the control of internal drainage, relief, rate of evaporation, distribution of rainfall, and amount of rainfall. The extent as well as the nature of leaching is collectively significant for determining the process of chemical weathering. Reduction and oxidation are specifically considered whether controlled by valence of the ions in the minerals, texture of the material, etc.
