At 2010K, the equilibrium constant Kc is 4*10^-4 for the following:
If the equilibrium concentration of N2 is .28M and O2 is .38M, what is the equilibrium concentration of NO?
To quote one of our very good math and science tutors: “You will find here at Jiskha that long series of questions, posted with no evidence of effort or thought by the person posting, will not be answered. We will gladly respond to your future questions in which your thoughts are included.”
I have removed your other 6 posts. You are welcome to post again, but be sure you include what you know about each question so far and what your SPECIFIC QUESTION is.
Kc = (NO)^2/(N2)(O2)
You have only one unknown. Solve for that.
