一、选择题

1．一定温度下，向容积为4L的密闭容器中通入两种气体发生化学反应，反应中各物质的物质的量变化如图所示，下列对反应的推断合理的是

A．该反应的化学方程式为3B+4C⇌6A+3D

B．反应进行到1s时，υ(A)=υ(D)

C．反应进行到6s时，各物质的反应速率相等

D．反应进行到6s时，B的平均反应速率为0.025mol⋅(L⋅s)−1

2．一定温度下，在密闭容器中进行反应：4A(s )+3B(g)2C(g)+D(g)，经2min，B的浓度减少0.6mol•L﹣1．对此反应的反应速率的表示，正确的是( )

①在2min内，用C表示的反应速率是0.1mol•L﹣1•min﹣1

②反应的过程中，只增加A的量，反应速率不变

③2分钟内，D的物质的量增加0.2 mol

④分别用B、C、D表示的反应速率其比值为3:2:1

A．①② B．③ C．① D．②④

3．已知：①S(g) +O2(g)= SO2(g) △H1 ②S(s)+O2(g)=SO2(g) △H2，下列说法正确的是

A．硫燃烧过程中将化学能转化全部为热能

B．相同条件下，1 mol S(s) 比l mol S(g) 燃烧更剧烈

C．两个过程的能量变化可用下图表示，△H1＜△H2＜0

D．两个反应中反应物的总键能都比生成物的总键能小

4．对可逆反应4NH3(g)+5O2(g)⇌4NO(g)+6H2O(g)，下列叙述正确的是

A．达到化学平衡时，6v正(O2)=5v逆(H2O)

B．化学反应速率关系是：2v正(NH3)=3v逆(H2O) C．达到化学平衡时，若增加容器体积，则正反应速率减小，逆反应速率增大

D．若单位时间内生成xmolNO的同时，消耗xmolNH3，则反应达到平衡状态
