The value of K c for the reaction NO(g) ⇌ 1/2N 2 (g) + 1/2O 2 (g) at the same temperature. 反应2NO(g)+O2(g)2NO2(g)实验数据如下表. n2 (g) o2 (g) 2no (g) Get the answers you need, now!. 6 kJ and Δ S° = -198. 相关试题【7】 为什么n2+2o2=2no2是错的. 0 kj with -180. 48x10^4 at 184C. 7 × 10 –13 (in the second step, since the reaction is reversed, the Kc will be the inverse) Add the two steps to get the overall reaction. N2(g) + O2(g) 2NO(g) Using the standard thermodynamic data in the tables linked above, calculate the equilibrium constant for this reaction at 298. The rxn is endothermic and delta H will be zero. 5 KJ B: NO(g) + O2(g) → NO2(g) AH = -57. N2(g)+O2(g)⇌2NO(g), K1 = 4. Studying for my final and Im stuck on this problem From the following data: N2(g)+ 3/2O2(g) = N2O3 (s) ∆H= 83. Therefore, the equilibrium constant, in presence of the catalyst, at 2000 K is: (A) 40 × 10 ‒4 (B) 4 × 10 ‒4 (C) 4 × 10 ‒3 (D) Difficult to compute without more data. 2kJ use Hess's law to calculate ΔH for the reaction N2O(g)+NO2(g)→3NO(g) Express your answer using four significant figures. What is the answers to module 18 foolproof. 10 at 2000 °C. So, in case you're taking #4 , you have: 2NO(g) + O2(g) -----> 2NO2(g) deltaH = -114. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. N2(g) + O2(g) → 2NO(g); ΔH = +180. 4k points) equilibrium. Given the following information: 2NO(g) + O2(g) ­­­> 2NO2(g) ΔH = ­116 kJ 2N2(g) + 5O2(g) + 2H2O(l) ­­­> 4HNO3(aq) ΔH = ­256 kJ N2(g) + O2(g) ­­­> 2NO(g) ΔH = +183 kJ Calculate the enthalpy change for the reaction below:. The rxn is endothermic and delta H will be negative b. We do this by measuring the.
