❤ WHAT IS A CATALYST? ❤
➡ Catalyst is a chemical substance which is used in a chemical reaction which is used to accelerate or decelerate the rate at which the reaction OCCUR without being used up.
❤ INVOLVEMENT OF POTASSIUM CHLORATE (KCLO3) ❤
➡ Potassium Chlorate decpmposes only at 700°C and even then the rate of release of oxygen is very slow. But when potassium chlorate is heated in the PRESENCE of MANGANESE DIOXIDE, decomposition begins at a much lower temperature, 300°C, and manganese dioxide remains unaffected. Thus, in this reaction, manganese dioxide acts as a catalyst.
❤ REACTION ❤
➡ 2KClO3 -----MnO2-----> 2KCl + 3O2
