Determine the equilibrium constant?

Question

Determine the equilibrium constant for the reaction below given the following concentrations at equilibrium:

NO_2(g) + CO_(g) ↔  NO_(g) + CO_2(g)

1. [NO₂]= 0.040 mol/L
2. [CO]= 0.033 mol/L
3. [NO] = 1.7 mol/L
4. [CO₂] = 3.0 mol/L

K_c=  abcd?  is 4 digit answer

Answer 1

NO_2(g) + CO_(g) ↔  NO_(g) + CO_2(g) ... balanced equation

Keq = [NO][CO₂]/[NO₂][CO] = (1.7)(3.0)/(0.04)(0.033) = 3.9x10³
