Do they sound natural?
1.something that makes a chemical reaction happen more quickly without itself being changed.( Do we use happens or happen in this sentence?)
2.The magic has displaced this monkey to what it was in the movie.

Question

Answer

1) happen. The phrase seems to be missing a subject and a verb:
[A catalyst is] something that makes a chemical reaction happen more quickly without itself being changed.

2) The sentence does not sound normal. I can't figure out what you are trying to say about the monkey or the movie.

Answer

Jordan is right for sentence 1.
Sentence 2. - Do you mean 'The magic has changed the monkey back into what it was in the movie' ?
Still sounds awkward. What's the rest of the paragraph?
