Since the CB3-111 only has a 16GB (non-upgradeable) eMMC drive, it may be a good idea to install Arch Linux on a fast USB 3.0 drive rather than the internal drive. This will allow you to boot into ChromeOS as well as Arch Linux. Make sure to use a fast drive, since not just any drive will provide a comfortable experience.
