The Total solution for NCERT class 6-12
A sample of HI(g) is placed in flaskat a pressure of 0.2 atm. At equilibrium the partial pressure of HI(g) is 0.04 atm. Whatis Kp for the given equilibrium?
Theinitial concentration of HI is 0.2 atm. At equilibrium, it has a partialpressure of 0.04 atm. Therefore, a decrease in the pressure of HI is 0.2 – 0.04= 0.16. The given reaction is:
Therefore,
Hence,the value of Kp for the given equilibrium is 4.0.
