Question

已知一氧化碳与水蒸气的反应为：CO(g)+H2O(g) ( 可逆)===CO2(g)+H2(g)

Answer 1

K°=Kp*(1/p°)^Δν=Kc*(RT/p°)^Δν

Δν=0,所以K°=Kp=Kc

CO(g) + H2O(g) ←→ CO2(g) + H2(g)

初0.01 0.01 0 0

转 x x x x

平0.01-x 0.01-x x x

Kc=x²/(0.01-x)²=9.4

x²=9.4*(0.01-x)²

8.4x²-0.188x+0.00094=0

x₁=0.01484(舍),x₂=0.00754

所以一氧化碳的转化率α(CO)=0.00754/0.01*100%=75.4%
