Question

Which explanation describes the last part of a chemical reaction?

Reactants collide to form a transition state.


Transition state falls apart to form products.


Products collide to form reactants.


Reactants collide to form products.

I am not sure between Reactants collide to form a transition state and Transition state falls apart to form products. please put an explanation.

Answer 1

Transition state falls apart to form products.

Step-by-step explanation:

Reactants collide to form a transition state is actually the initial step (not the last step) because reactants have react with each other. Transition state is the middle stage, once this stage falls or passes, you get products. I have attached an example reaction scheme to better understand.
