The equation of a curve is \(y = \ln x + \frac{2}{x}\), where \(x > 0\).

(i) Find the coordinates of the stationary point of the curve and determine whether it is a maximum or a minimum point.

(ii) The sequence of values given by the iterative formula \(x_{n+1} = \frac{2}{3 - \ln x_n}\), with initial value \(x_1 = 1\), converges to \(\alpha\). State an equation satisfied by \(\alpha\), and hence show that \(\alpha\) is the \(x\)-coordinate of a point on the curve where \(y = 3\).

(iii) Use this iterative formula to find \(\alpha\) correct to 2 decimal places, showing the result of each iteration.
