2.1. Use fzero() to determine the solution to the polynomial below. cos (VIP(x)l) -sin(x) = 0 (fzero)| y = x3 - 2 P(x) = polyfit(x, y,7) (8) 2.2. The reaction A + B takes place in a liquid-phase batch reactor at a constant temperature. The initial concentration of A is 1.2 mol/L. Determine the time required to achieve 75 % of the maximum possible conversion if the forward reaction is second order and the reverse reaction is first order: kį = 0.4 moLmin and k, = 0.1 min-1. Hint: TA = -k,C, + k,Gg CA = CA0 - x = 1.2 - x C = Cgo + x = 0+x = x %3D For maximum conversion dCA TA = = 0 dt TA = -0.4(1.2 – x)² + 0.1x = 0 Simplify and determine the roots of the equation.
