Equilibrium Concentration of NO in N2/O2 Mixture at 2000 K

[jlc287]

Considering the following N2+ O2= 2NO at 2000 K is 4.0 × 10-4. Consider an initial mixure of 10 moles of N2 and and one mole of O2.

How do I find the concentration of NO in the equilibrium mixture in ppm?

thank you

4.0 × 10-4

What is this? An equilibrium constant? You need to present the question clearly and show your attempt at solving it.
