Calculate The Equilibrium Concentrations Of N2O4and NO2 At

Dinitrogentetraoxide partially decomposes according to the following equilibrium: N2O4 (g) ⇌ 2NO2 (g) A 1.00 L flask is charged with 0.0400 mol of N2O4 at 373 K. An equilibrium is established after some time and only 0.0055 mol of N2O4 remains. What is KC for this reaction? Select one: a. Kc = 0.866 b. Kc = 0.216 c. Kc = 12.5 d.[2ΔS f (NO2 (g))] - [1ΔS f (N2O4 (g))] [2(239.95)] - [1(304.18)] = 175.72 J/K 175.72 J/K (increase in entropy)Answer to A chemist measures the energy change ΔH during the following reaction: 2NO2(g)→N2O4(g) ΔH=−55.3kJ Use the informa...The reaction N2O4 (g) ↔ 2NO2 (g) is an equilibrium reaction at some temperature with an equilibrium constant K = 4.00 x 10−7.

2NO2(g) ⇌ N2O4(g) Keq= [N2O4(g)] / [NO2(g)]^2. substituting the given data we get . 1.15 = [N2O4(g)] / ( 0.50)^2 [N2O4(g)] = 1.15 * ( 0.50)^2 = 0.2875 moles / literAt a particular temperature, Kp = 0.370 for the reaction N2O4(g) 2NO2(g) A flask containing only N2O4(g) at an initial pressure of 3.20 atm is allowed to reach equilibrium. Calculate the total pressure in this flask at equilibrium. I need some serious help..I'v tried everything with this problem...this is what i tried before and it doesnt work. Kp for the reaction can be written as Kp= ((pNO22 NO 2 (g) <=> N 2 O 4 (g) The standard enthalpy (delta H� = -57.2 kJ) and the entropy (delta S� = -175.83 kJ) of reaction can be calculated from the follow standard-state enthalpies of formation and standard-state entropies.Answer to: Consider the following reversible reaction: N2O4(g) arrow 2NO2(g) a. If we add in more NO2, we will force the reaction further to the....

The computer animation needs to be re-built. A YouTube video of this demonstration is availableCalorimetric studies show that the reaction is exothermic. 2NO2(g) N2O4(g) + 14.1 kcal. Based on this information, which one--if any--of the following additional changes would increase the molar concentration at equilibrium of N2O4(g)? decrease the pressure increase the temperature decrease the concentration of NO2(g) stir the reaction mixture

IMO this can be a bit garbled (I'm now not blaming you for that!).

I feel is is how it is meant to be solved.

2NO2(g) → N2O4(g)

Kp = P(merchandise)/P(reactants) = (P(N2O4))/((P(NO2))^2)

Kp = (1.64 atm)/((0.38 atm)^2) = 11.36 atm^-1

Next we want to convert Kp to Kc:

Kp = Kc(RT)^Δngas

So

Kc = Kp/((RT)^Δngas)

Δngas = Mole of gasoline (product) - Mole of Gas (Reactant) = 1 - 2 = -1

R = 0.08206 L atm Ok^-1 mol^-1

T = 298 Okay

Kc = Kp/((RT)^Δngas) = (11.36 atm^-1)/(((0.08206 L atm K^-1 mol^-1)*(298 Ok))^-1)

Kc = 277.8 L mol-1

Now we use this to calculate ∆G.

∆G = -RT(lnKeq)

http://www.chem.purdue.edu/gchelp/howtosolveit/The...

R = 0.008314 kJ mol^-1 Okay^-1

T = 298 Ok

Keq = Kc = 277.8

∆G = -RT(lnKeq)

∆G = -(0.008314 kJ mol^-1 Okay^-1)*(298 Okay)*(ln(277.8))

∆G = 13.94 kJ mol^-1
