Both can convey a small event causing much larger events, but a chain reaction generally refers to something that has one fixed sequence (even if that sequence is unknown beforehand).
A lead to B leads to C leads to D. A will always set off a sequence that leads to D in this way. Like a lined up set of dominoes.
A butterfly effect refers to a small change that has large, but seemingly random effects. The common phrase is “a butterfly flaps its wings in (city A) and you get rain instead of sunshine in (city B)”. Because weather is so complex, small changes (ie air pressure from wings flapping) can cause bigger and bigger changes, but predicting what is virtually impossible
Imagine instead of dominoes lined up, you have many set up on the floor randomly, some clues together, some not. Now toss a marble into the room. The marble may only knock over a few dominoes, but more and more will fall, yet it’s almost impossible to predict **which** ones will fall
