part b) please. find the differential eqn for each time

The second-order reaction A+BC is carried out in a batch reactor at 35C. The specific rate constant is 0.0455L/(molmin). The reactor is filled with 1000 . L and the concentration of each species is 2.0M. a) What is the conversion after 10.,50. , and 100. minutes? b) If this reaction were elementary and reversible with an equilibrium constant of Ke=1.22, what is the conversion after 10., 50., and 100. minutes? Set up and simplify the differential equation, but do not solve it
