The Total solution for NCERT class 6-12
Dihydrogen gas used in Haber’s process isproduced by reacting methane from natural gas with high temperature steam. Thefirst stage of two stage reaction involves the formation of CO and H2. In second stage, COformed in first stage is reacted with more steam in water gas shift reaction,
If a reaction vessel at 400°C is charged with anequimolar mixture of CO and steam such that 4.0 bar, what will be the partial pressureof H2 at equilibrium? Kp= 10.1at 400°C
Let the partial pressure of both carbondioxide and hydrogen gas be p. The given reaction is:
It is
Now,
Hence,at equilibrium, the partial pressure of H2 will be 3.04 bar.
