Comparing Reaction Rates By Gas Collection Kit

If your students have ever questioned why some reactions go very quickly while others tend to take forever, this lab allows them to find out for themselves. Using a method that makes determining the “rate” of reaction simple and quantitatively accurate, students quickly see how varying concentration or temperature or adding a catalyst affects the rate of a reaction. Developed by Mary Gallup.
