Q.4 In some chemical reactions, the rate at which the amount of substance changes with time is proportional to the amount present. For the change of d-glucono lactone into gluconic acid, for example, dy = -0.6y dt when t is measured in hours. If there are 100g of ô-glucono lactone present when t=0, how many grams will be left after the first hour?
