Let q(t) represent the amount of a certain reactant present at time t. suppose that the rate of decrease of q(t) is proportional to q3(t). that is, q =−kq3, where k is a positive constant of proportionality. how long will it take for the reactant to be reduced to one half of its original amount? recall that, in problems of radioactive decay where the differential equation has the form q =−kq, the half-life was independent of the amount of material initially present. what happens in this case? does half-life depend on q(0), the amount initially present?
