At a certain temperature and a total pressure of `10^(5)` Pa, iodine vaour contain 40% by volume of iodine atmos `[I_(2) (g) hArr 2 I (g) ]. " Calculate " K_(p)` for the equilibrium.

Explanation

Partial pressure of I atoms `p_(1) = 40/100 xx 10^(5) Pa = 0*4 xx10^(5) Pa `
Partial pressure of `I_(2) (P_(I_(2)))= 60/100 xx 10^(5) Pa = 0*60 xx 10^(5) Pa `
`k_(p) = (p_I^(2))/p_I^(2) = ( 0*4 xx10^(5))^(2) /(0*60 xx 10^(5) )= 2*67 xx 10^(4) Pa` `k_(p) = (p_I^(2))/p_I^(2) = ( 0*4 xx10^(5))^(2) /(0*60 xx 10^(5) )= 2*67 xx 10^(4) Pa``k_(p) = (p_I^(2))/p_I^(2) = ( 0*4 xx10^(5))^(2) /(0*60 xx 10^(5) )= 2*67 xx 10^(4) Pa`
