The equilibrium constant, kc, for the reaction n2o4 (g) ⇄ 2no2 (g) is 0.211 at 100°c. if the equilibrium concentration of n2o4 is 0.00251 m, calculate the equilibrium concentration of no2. view available hint(s) the equilibrium constant, kc, for the reaction n2o4 (g) ⇄ 2no2 (g) is 0.211 at 100°c. if the equilibrium concentration of n2o4 is 0.00251 m, calculate the equilibrium concentration of no2. 2.65 × 10-4 m 0.0230 m 2.99 × 10-5 m 5.30 × 10-4 m

The concentration of NO₂ is 0,0230M

Explanation:

The equilibrium constant, kc, express the ratio in equilibrium between products and reactants. For the reaction:

N₂O₄(g) ⇄ 2NO₂ (g) kc = 0.211 at 100°C

kc =

In equilibrium:

0,211 =

5,2961x10⁻⁴ = [NO₂]²

0,0230 M = [NO₂]

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
