Quiz 3 Prep Quiz #8

The question states:
"The reaction N2(g) + O2(g) = 2NO (g) contributes to air pollution whenever a fuel is burned in air at a high temperature. At 1500 K, Kc = 1.0x10^-5. A sample of air is heated in a closed container to 1500 K. Before any reaction occurs [N2] = 0.80 M and [O2] = 0.20 M. Calculate the equilibrium concentration of NO."

It emphasizes that air is heated in a closed container to 1500 K, but does the temperature affect how you solve the problem? Thanks in advance!

I don't believe that the temperature affects how you solve the problem at all...it just tells you the Kc at that temperature. You should still just set up an ICE box and solve the quadratic equation for x, allowing you to solve for the concentration asked for.
