填空题

煤炭燃烧过程中会释放出大量的SO2,严重破坏生态环境。采用一定的脱硫技术可以把硫元素以CaSO4的形式固定,从而降低SO2的排放。但是煤炭燃烧过程中产生的CO又会与CaSO4发生化学反应,降低脱硫效率。相关反应的热化学方程式如下:

CaSO4(s)+CO(g) CaO(s) + SO2(g) + CO2(g)    ΔH1=218.4kJ·mol-1(反应Ⅰ)

CaSO4(s)+4CO(g) CaS(s) + 4CO2(g)    ΔH2= -175.6kJ·mol-1(反应Ⅱ)

请回答下列问题:

(1)反应Ⅰ能自发进行的条件是           

(2)对于气体参与的反应,表示平衡常数Kp时用气体组分(B)的平衡压强p(B)代替该气体物质的量浓度c(B),则反应Ⅱ的Kp=       (用表达式表示)。

(3)假设某温度下,反应Ⅰ的速率(v1)大于反应Ⅱ的速率(v2),则下列反应过程能量变化示意图正确的是            

(4)通过监测反应体系中气体浓度的变化判断反应Ⅰ和Ⅱ是否同时发生,理由是            

(5)图1为实验测得不同温度下反应体系中CO初始体积百分数与平衡时固体产物中CaS质量百分数的关系曲线。则降低该反应体系中SO2生成量的措施有        

A.向该反应体系中投入石灰石

B.在合适的温度区间内控制较低的反应温度

C.提高CO的初始体积百分数

D.提高反应体系的温度

(6)恒温恒容条件下,假设反应Ⅰ和Ⅱ同时发生,且v1>v2,请在图2中画出反应体系中c(SO2)随时间t变化的总趋势图。
