two most abundant atmospheric gases react to a small extent at 298K in the presence of a catalyst to achieve dynamic equilibrium:

N2(g) + O2(g) ->/<- 2NO(g) Kp= 0.30

Partial pressure of N2 and O2 = 0.78atm
1dm3 flask and equilibrium established after 30min.

temperature of system raised to 350K at 40min and equilibrium re-established at 60min. calculate the presssure of N2 and NO at 70min

  1. 1. Is the 0.78 atm the partial pressure to start or after equilibrium is established?

    2. What's the new Kp (or Kc) at 350K?
    I suggest you repost the question at the top of the page and include the information in answer to the questions 1 and 2.
