As we have learned

Acidity of oxides in periodic table -

Acidic character of oxides increases across the period 

-

 

 Acidic strength of oxide depends on two factors 

1) electronegativity of central atom 

2) oxidation number of central atom 

For two diffrent atom oxidation number is dominating factor so the order of acidic strength is 

P_2O_5 > SO_2> CO_2> B_2O_3
