What is the analytical solution to this nonlinear ODE at the bottom (use judicious substitution). The k's are constants. yQ and yA are functions of time. dya = -k1y k3y = -koy (ko = k + kg) = dt dyq = ky k2yQ dt ys = 1-ya-ye Selectivity = dyq dya = ky kuya -koya Find the analytical solution for: dyQ dya k2 yo ko y k1 ko
