if u understand no.1 then u shud'nt be hving problem with 2 as well! simple! alveloar PO2 equilibrates with capillary PO2 ... capillary leavng the alveolus with higher PO2 (X) will hv higher PO2, less CO2 and subsequently high pH! on the contrary,capillary passing through alveolus with lower PO2 will hv higher CO2 ans lesser pH!
