question 21,22

Answer 1

21) A Catalyst is a substance that speeds up a Chemical reaction without itself being consumed in the reaction. Explanaties :- 2.- AG A Gtahst speeds up a Chemical reactors by providing an alternate Path having lower activatins energ. ati composites remains same. It may undergo Change in physical state 22) One of the differences between a voltaic cell and an electrolytic cell is that in an electrolytic cell, A) a non spontaniors reaction is forced to occur. Explanations :- In an electrolytic cell, process is carried out with the help of a battey. Here a nonsfontanos process í Carried out by Converter electrical energy into Chemical energy. Ex: Electrolysis aporal Natte Na (non spontany), á até (nonsfont)
