题目内容
已知:O2(g) = O2+(g)+e- H1=" +1175.7" kJ·mol-1
PtF6-(g) =PtF6(g)+e- H2=" +771.1" kJ·mol-1
O2+(g)+PtF6-(g) =O2PtF6(S) H3=" -482.2" kJ·mol-1
则反应O2(g)+PtF6(g) = O2PtF6 (s)的H是
PtF6-(g) =PtF6(g)+e- H2=" +771.1" kJ·mol-1
O2+(g)+PtF6-(g) =O2PtF6(S) H3=" -482.2" kJ·mol-1
则反应O2(g)+PtF6(g) = O2PtF6 (s)的H是
A.77.6 kJ | B.-77.6 kJ·mol-1 | C.+77.6kJ·mol-1 | D.-886.8kJ·mol-1 |
