Process:  - Coal is burned - Sulfur in the coal combines with oxygen to form sulfur oxides - The sulfur oxides are released into the atmosphere - The sulfides combine with oxygen in the atmosphere to form sulfur trioxide - The sulfur trioxide reacts with water in the atmosphere to form sulfuric acid, a very strong acid - The sulfuric acid makes the rain acidic -   Perturbation hypothesis: suppose bubbles take longer to form happens, how will it affect MORE acid rain.  Does the supposed perturbation have an effect (direct or indirect) on the process?

no
