First Order processes
This page will present questions based upon first order processes, either radioactive decays or chemical reactions. When you press "New Problem", a window with a question and a submit form will be opened. You may have to reposition the new window the first time it opens. Obtain and submit the required answer. Results appear on the main window. Use the "e" notation for presnting very large or small numbers. All masses are in grams, but the time dimension will vary.
