Calculate the composition of dry air at 3800 K and 1 bar. Take the initial composition as 0.78 mol N2, 0.21 mol O2, and 0.01 mol Ar. Neglect the ionization of NO.
Using the NIST-JANAF tables, thermodynamic values are found.
I'm confused about how to find K1 and K2 of the two reactions below. The temperature given is 3800 K and the standard pressure is 1 bar.
K1 = 0.0895 and K2 = 2.221
I don't know if the values of K1 and K2 are right.
(1) N2 + O2 = 2NO
(2) 02 = 2O
Steps
1. Create an icebox chart
2. Find K1 and K2 using the thermodynamic values from the NIST-JANAF tables
3. To solve for (a) and (b) in the icebox chart ---- divide the 1st equation (K1) by the 2nd equation (K2) and solve for (a) as a function of (b)
4. Find the moles of N2, O, O2, NO from the icebox chart once (a) and (b) values are found. And the moles of Ar are given.
