Question

1) What are the steps involved in chain reactions

2) Collision theory was proposed by?

3) Reactions can be broadly classified into depending on time of reaction.

4) What is the best part of the activated complex [ one line answer ]

Answer 1

1) There are three steps in chain reactions ; They are as follows :-
>> Chain initiation
>> Chain propagation
>> Chain termination

2) Collision theory was proposed by Arrhenius

3) Reactions can be broadly classified into three types depending on time of reaction.

>> Moderate reactions.
>> Spontaneous reactions
>> Very slow reactions.


4) The best of the activated complex is that it will form products compulsorily or may break down into reactants again.

Hope helped!
