about some chemestry reaction

For any reaction, the rate is affected by changes in temperature, concentration of reactants, reactant surface, and the addition of catalysts. Controlling the rate of reaction by changing certain reaction conditions is essential for either slow down unwanted reactions or accelerate chemical processes to increase productivity.

Explain the mechanism of cleansing action of soaps and detergent?

Hydrocarbon portion is non polar, hydrophobic and soluble in oils and greases but not in water.
