I dont know why but me too
Answer:
D. 5.0
Explanation:
Step 1: Write the balanced equation at equilibrium
2 NO₂(g) ⇄ N₂O₄(g)
Step 2: Calculate the concentration equilibrium constant
The concentration equilibrium constant (Kc) is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients.
Kc = [N₂O₄]/[NO₂]² = 0.2 / 0.2² = 5
Explanation:
What would be the new volume if the pressure on 600 mL is increased from 90 kPa to 150 kPa? V = Pu V₂ = 360 mL ~ 400 mL 6.
