1Answer to Reaction: 3H2(g) + N2(g) = 2NH3(g) The value of Kp for the reaction is 4.3x10^4 at 648 K. Determine the equilibrium partial pressure of NH3 in a reaction vessel that initially contained 0.900 atm N2 and 0.500 atm H2 at 648 K. Agaseous hydrocarbon gives upon combustion 0.72g 0.72 g of water and 3.08g 3.08 g of CO2 C O 2. The empirical formula of the hydrocarbon is Answer 5. The density of 3M 3 M solution of sodium chloride is 1.252gmL−1 1.252 g m L − 1. The molality of the solution will be: (molar mass, N aCl=585gmol−1 N a C l = 585 g m o l − 1) Answer 6. N2g) + 3H2(g) -----> 2NH3(g) ; ∆rH° = -92.4 KJ/mol enthalpy of formation of NH3 means heat released in the formation of 1 mole of NH3 . so, divide both sides by 2 in above reaction 1/2N2(g) + 3/2H2(g) ---> NH3(g) ; Therefore , ∆fH° = ∆rH°/2 = -92.4/2 = 46.2 KJ/mol .

N2g) + 3H2(g) 2NH3(g) (H = -92 KJ mol-1. What is the effect of using an iron . catalyst. on the position of equilibrium? Is this an example of homogeneous or heterogeneous catalysis? Propose a mechanism, use the words adsorb, bond and diffuse. N2(g) + 3H2(g) 2NH3(g) (H =

N2g) + 3H2(g) 2NH3(g) Determina el reactivo limitante en cada una de las siguientes mezclas: a) 3.0 moles de N2 y 5.0 moles de H2 b) 8.0 moles de N2 y 4.0 moles de H2 2 Ver respuestas Publicidad Publicidad XannXnails XannXnails a) 3mol H2 ----- 1mol N2. 5mol H2 ----x= 1,66mol N2.
2NH3g) --> 3H2(g) + N2(g) The equlibrium constant is the ratio of the concentration of products to that of reactants. Keq = [Products] / [Reactants] So to write the expression, we have to identify our reactants and products. Reactants = NH3 . Products = H2 and N2. Amoniadapat dibuat melalui reaksi : - 2249516 Amonia dapat dibuat melalui reaksi : N2(g) + 3H2(g) --> 2NH3 (g) jika 60 liter gas nitrogen direaksikan dengan 240 liter gas hidrogen yang diukur pada suhu dan tekanan yang sama, maka datareaksi: N2 (g)+ 3H2→ (g) 2NH3 (g) Pada P dan T tertentu sebagai berikut.
