14.解析:(1)前2 s内Δc(NO)=-7.5×10-4 mol·L-1,根据化学方程式可知,Δc(N2)=3.75×10-4 mol·L-1,则结合速率公式可知v(N2)==1.875×10-4 mol·L-1·s-1;4 s后CO和NO的浓度保持不变,则说明反应到4 s时达到平衡状态。(2)t1时,正反应速率大于逆反应速率,则反应未达到平衡,反应向正反应方向进行,所以NO2的浓度在减小,故a正确;t2时,正、逆反应速率相等,反应达平衡状态,化学平衡为动态平衡,反应没有停止,故b错误;t2~t3为平衡状态,各物质的浓度不再变化,但浓度不一定相等,故c正确,d错误;O~t2正反应速率大于逆反应速率,反应未达到平衡,反应向正反应方向进行,所以N2O4的浓度增大,故e正确;反应过程中,N2O4的浓度增大,气体的颜色变浅,故f错误;建立平衡过程中,N2O4浓度增大,NO2浓度减小,混合气体平均相对分子质量增大,g正确。
