A reaction mixture initially contains 0.86 atm NO and 0.86 atm SO3. Determine the equilibrium pressure of NO2 if Kp for the reaction at this temperature is 0.0118. NO(g) SO3(g) NO2(g) SO2(g)

Explanation:

Reaction equation for this reaction is as follows.

It is given that = 0.0118.

According to the ICE table,

Initial:           0.86      0.86               0            0

Change:          -x          -x                 +x           +x

Equilibrium:  0.86 - x   0.86 - x         x           x

Hence, value of will be calculated as follows.

         0.0118 =

             x = 0.084 atm

Thus, we can conclude that is 0.084 atm.
