25. First-order chemical reactions In some chemical reactions, the rate at which the amount of a substance changes with time is proportional to the amount present. For the change of S-glucono lactone into gluconic acid, for example, dy/dt = -0.6 when t is measured in hours. If there are 100 grams of 8-glucono lactone present when t = 0, how many grams will be left after the first hour?
