尿素(H2NCONH2)是一种非常重要的高氮化肥,工业上合成尿素的反应如下:2NH3(l)+CO2(g)H2O(l)

+H2NCONH2(l) △H=-103. 7kJ/mol

试回答下列问题:

(1)下列措施中有利于提高尿素的产率的是_____。

A.采用高温 B.采用高压 C.寻找更高效的催化剂

(2)合成尿素的反应在进行时分为如下两步:

第一步:2NH3(l)+CO2(g)H2NCOONH4(氨基甲酸铵)(l) △H1

第二步:H2NCOONH4(l)H2O(l)+H2NCONH2(l) △H2

某实验小组模拟工业上合成尿素的条件,在一体积为0.5 L的密闭容器中投入4 mol氨和1mol二氧化碳,实验测得反应中各组分随时间的变化如甲图所示:

①已知总反应的快慢由慢的一步决定,则合成尿素总反应的快慢由第___ 步反应决定,总反应进行到

____min时到达平衡。

②反应进行到10 min时测得CO2的物质的量如甲图所示,则用CO2表示的第一步反应的速率v(CO2)=

________。

③第二步反应的平衡常数K随温度的变化如乙图所示,则△H2____0 (填“>”“<”或“=”)。
