Question: Bimolecular chemical reactions A bimolecular chemical reaction is one in which two chemicals react to form another substance. Suppose that one molecule of each of the two chemicals reacts to form two molecules of a new substance. If x represents the number of molecules of the new substance at time t, then the rate of change of x is proportional to the product of the numbers of molecules of the original chemicals available to be converted. That is, if each of the chemicals initially contained A molecules, then
dx/dt = k(A - x)2
If 40% of the initial amount A is converted after 1 hour, how long will it be before 90% is converted?
