1.	How does the rate of a reaction depend upon the catalyst ?Give a suitable example.
Answer» Solution :(1) The SUBSTANCE in whose in whose presence the rate of a chemical reaction changes, without causing any chemical change to it , is called a catalyset. (2) On heating potassium chlorate ` (KCIO_(3))`decomposes into potassium chloride and oxygen slowly. ` 2KCIO_(3) overset(Delta)to 2KCI + 3O_(2)...` The rate of the above reaction neither increases by reducing the particle size nor by increasing the reaction TEMPERATURE . However in the presence of MANGANESE dioxide , ` KCIO_(3)` decomposes at a comparatively lower temperature and oxygen is produced more briskly. No Chemical change takes place in ` MnO_(2)`in this reaction. It acts as catalyset.
