Question

At a certain temperature and total pressure of 10⁵Pa, iodine vapour contains 40% by volume of I atoms I₂ (g) ⇆ 2I (g) Calculate $K_{p}$ for the equilibrium.

Answer 1

sorry I can't understand that what u have written in last line..plz ..clarify it to me....

Answer 2

Partial pressure of 1 atoms = P1= 40/100 X P total ,

=40/100 x 105,

= 4x104 Pa.

partial pressure of I2 molecules,

PI2= 60/100 x105, 6x104 pa.

now you have to give reaction of Kp=( 4x104)2/ 6x 104= 2.67 x104 Pa .

hope this answer is provide best choice with no risk of it .it provides best choice with no trouble of it.
