20. The Brusselator. This hypothetical system was first proposed by a group work-ing in Brussels [see Prigogine and Lefever (1968)] in connection with spatiallynonuniform chemical patterns. Because certain steps involve trimolecular reactions, it is not a model of any real chemical system but rather a prototype thathas been studied extensively. The reaction steps areA-X.B+X-Y+D.2X+ Y-3X,X-E.305It is assumed that concentrations of A, B, D, and E are kept artificially constant so that only X and Y vary with time.(a) Show that if all rate constants are chosen appropriately, the equations describing a Brusselator are:dtA-(B+ 1)x + x²y,dy=Bx-x²y.di

1. The concept of gas collisions can be applied to the study of metrology. Being the highest composition in atmospheric air (78% by volume), N2 has a collision diameter of 0.369 x 10° m. At 298 K and 1 atm, calculate the single collision frequency of N2 at sea level. The collision frequency of N2 decreases at higher altitude. At 11 km from the sea level, the collision frequency is 3.16 x 10° s-1. Calculate the pressure of the gas at this altitude (T = – 220 K).
