To evaluate the given limit:

$\lim_{x \to \left(\frac{\pi}{2}\right)^-} \frac{\arccos x}{\pi - 2x},$

let us proceed step by step.

Step 1: Analyze the behavior of the numerator ($\arccos x$)

The $\arccos x$ function approaches $\arccos\left(\cos\frac{\pi}{2}\right) = \frac{\pi}{2}$ as $x$ approaches 1 (from the left). However, as $x \to \frac{\pi}{2}^-$, the exact functional behavior will depend on substitution for clarity.
