Question
Consider the equilibrium system described by the chemical reaction below, which has a value of Kc equal to 4.10 × 10⁻⁴ at a high temperature. If 0.20 mol N₂ and 0.15 mol O₂ react in a 1.0 L vessel, what will the equilibrium concentration of O₂ be?
N₂(g) + O₂(g) ⇌ 2 NO(g)
 
 
A )Set up the expression for Qc and then evaluate it to determine the direction of the reaction. Do not combine or simplify terms.
  
Qc = _____/_____ = _____
 
Based on the given values and your value for Qc, set up ICE table in order to determine the unknown.     
 
 
Based on your ICE table, set up the expression for Kc in order to determine the unknown. Do not combine or simplify terms.
Kc = (________) / (_______)= 4.10 × 10⁻⁴
 
Based on your ICE table and expression for Kc, solve for the concentration of O₂ at equilibrium.
