某温度时,在5 L的容器中充入11.2 g CO和9 g H2O(g),使其发生CO(g)+H2O(g) CO2

某温度时,在5 L的容器中充入11.2 g CO和9 g H2O(g),使其发生CO(g)+H2O(g) CO2(g)+H2(g)的反应,如果CO的化学反应速率是0.01 mol·(L·s)-1,5 s后,容器内CO的浓度是________ mol·L-1,生成CO2为_________g,H2的化学反应速率是__________。

答案

解析:v(CO)=0.01 mol·L-1·s-1,5 s后,Δc(CO)=0.05 mol·L-1,起始

c(CO)=

=0.08 mol·L-1,所以5 s后,CO的浓度为0.08 mol·L-1-0.05 mol·L-1=0.03 mol·L-1

因为Δc(CO)=Δc(CO2)所以生成CO2的质量:0.5 mol·L-1×5 L×44 g· mol-1=11 g

v(H2)=v(CO)=0.01 mol·L-1·s-1

答案:0.03    11    0.01 mol·L-1s-1
