14.B【解析】反应Ⅰ和Ⅱ均为放热反应,升高温度,反应Ⅰ和Ⅱ的平衡均逆向移动,平衡常数均减小,A项正确;升高温度,反应速率加快,反应Ⅰ和Ⅱ的正反:应速率均增大,B项错误;900℃后,升高温度,反应Ⅰ平衡逆向移动,NO的产率降低,C项正确;800℃左右,NO的产率高,N2的产率低,D项正确

24.D【解析】pK,(HCOOH)pCCHCOc(HCOOH)J=Igc(HCOO-)·c(H+)_CCHCOOH)lgC(HCoOC(HCOOgc(H+)=pLc(HD3+pH,A项错误;弱电解质的电离吸热,升高温度,K。增大,CCHCOOpK,(HCOOH)减小,pC(HCOOH)]和pH均减小,则b线对应的温度低于a线,B项错误;由pH3.75、p[C(HCOOC(HCOOHD]=0可知,K,(HCOOH)10-35,C项错误;反应后的溶液是等浓度的HCOOH与HCOONa的混合溶液,K(HCOO-)K,(HCOH=10103
