已知：
O2(g) = O2+(g)+e－ △H1= +1175.7 kJ/mol
PtF6－(g) =PtF6(g)+e－ △H2= +771.1 kJ/mol
O2+(g)+PtF6－(g) =O2PtF6(s) △H3= -482.2 kJ/mol
则反应O2(g)+PtF6(g) = O2PtF6(s)的△H是
O2(g) = O2+(g)+e－ △H1= +1175.7 kJ/mol
PtF6－(g) =PtF6(g)+e－ △H2= +771.1 kJ/mol
O2+(g)+PtF6－(g) =O2PtF6(s) △H3= -482.2 kJ/mol
则反应O2(g)+PtF6(g) = O2PtF6(s)的△H是
