Answer: The initial partial pressures of
and
is 139.4 torr.
Explanation:
The equilibrium reaction is

initially conc. p p 0
At eqm. p-2x p-x 2x
Given: 

The expression for equilibrium constant is :

= 2x =115 torr
= (p-2x) = p-115 torr
= (p-x)= p-57.5 torr
Now put all the given values in this expression, we get


Therefore, the initial partial pressures of
and
is 139.4 torr.
