      In the atmosphere, reactions mostly depend on oxygen, and so long as it is present in about the same quantity, the reaction should be the same.

      Yes, if the reaction requires chemicals present in our atmosphere like oxygen which aren’t on the other planet, then the reaction will be different there. For example, you can’t have fire without oxygen!
