3.理论研究表明,在101kPa和298K下,HCN(g)HNC(g)异构化反应过程的能量变化如图所示。下列说法错误的是A.HCN比HNC稳定B.该异构化反应的H=+59.3kJmol^-1C.正反应的活化能大于逆反应的活化能D.使用催化剂,可以改变反应的反应热

10.取一支分液漏斗,向其中加入5mLCCl4,再加入约15mL溴水,塞上分液漏斗顶部的塞子,倒转过来充分振荡,然后置于铁架台上静置(如图所示),下列说法错误的是A.密度:CCl4>H2OB.溴在液体中的溶解度:CCl4>H2OC.静置一段时间后,打开顶部塞子,下层液体从下口放出,用另一个烧杯紧接着上层液体也从下口放出D.该实验表明,溴水中的溴大部分由水层转移到CCl4层中,使溴得以富集
