C. atoms are not close together
D. a catalyst is present.

    atoms that are not close together. let me know if im correct.

  • Science -

    You are correct. Atoms that are not close together. The reason is because when the atoms are not close together, it is going to need more energy to collide into each other than the ones with the high concentration that makes molecules and atoms easier to start chemical reaction which makes the amount of activation energy to be low.It applies for other two examples, too.
