5. In a bimolecular rcaction A + B -→ M, a moles per liter of a substance A and b molcs per liter of
a substance B are combined. Under constant temperature the rate of reaction is
y'=k(a-y)(b-y)
, that is, y' is proportional to the product of the concentration of the substances that are rcacting, wherd
P(r) is the number of moles per liter which have reacted after time 1. Solve this ODEi. assuming that utb.
