What are the factors on which the rate of reaction depends? Discuss each factor in brief. |

Answer» The rate of reaction depends upon the following factors:- (i) Concentration of the reactants:- Greater the concentration faster is the reaction. (ii) Presence of catalyst:- It increase the speed of the reaction by lowering the activation energy. (iii) Temperature:- The rate of reaction increases with increase of temp. in most of the case, the rate of reaction become almost double for every 10°C rise in temp. This is because of the increase in the number of effective collision with rise in temp. (iv) Surface area:- With increase in surface area rate of reaction increases. (v) Nature of reactants:- With change in reactants rate of reaction changes. |
