1. Many chemical reactions are the result of the interaction of two molecules that undergo a change toproduce a new product. The rate of the reaction typically depends on the concentrations of the twokinds of molecules. If a is the amount of substance A and b is the amount of substance B at time0, and if x is the amount of product at time t, then the rate of formation of x may be given bydxthe differential equation = k(a - x)(b - x), ork, where k is a constant for the(a - x)(b - x) dtt =dxdt=1=reaction. Integrate both sides of this equation to obtain a relation between x and t. Do this for botha = b and ab. Assume in each case that x = 0 when t = 0.2. Find the area of the region between the curve y = e¯¯ and the x-axis.
