Partial pressure of I atoms ( =mathrm{P} 1=40 / 100 times mathrm{P} ) total ( =40 / 100 times 10^{5} ) ( =4 times 10^{4} mathrm{Pa} ) Partial pressure of ( mathrm{I}_{2} ) molecules, ( mathrm{PI}_{2}=60 / 100 times mathrm{P} ) total ( =60 / 100 times 10^{5} ) ( =6 times 10^{4} mathrm{pa} ) now for the given reaction, ( mathrm{Kp}=(mathrm{pl})^{2} / mathrm{PI}_{2} ) ( =left(4 times 10^{4}right)^{2} / 6 times 10^{4} ) ( =2.67 times 10^{4} mathrm{Pa} )
