In Purdue's Chemistry department, the chemists have found that in a water based solution containing 1616 grams of certain undissolved chemicals, the rate of change of the amount of chemicals dissolved in the solution is proportional to the amount of the undissolved chemicals. Let Q(t)Q(t) (in grams) be the amount of dissolved chemicals at time tt and let kk be the positive proportionality constant. The differential equation describing the given situation is:
