If `CI_(2)` HCI and `O_2` are mixed in such a manner that the partial pressure of each is 2 atm and the mixture (V.P.=0.5 atm). What would be the approximate partial pressure of `CI_2` when equilibrium is attained at temperature (T)? If your answer in scientific notation is `xx x10^(-y)` ,write the value of y.
[Given:` 2H_2O(g)+2CI_2(g)hArr4HCI(g)+O_2(g),K_(p)=12xx10^(8)`atm)
