I am sorry, but they are related and cannot split them.

ac problems. Ask and the instructor to make sure you and your group all achieve the purposes. Ammonia, NH3, is one of the most important industrial substances in the world. Its synthesis is accomplished taking advantage of our understanding of the thermodynamic and kinetic factors that affect the chemical process. Synthesis and Thermodynamics: Most industrial ammonia is produced by combining N2(g) and H2(g). Relevant data for this synthesis reaction is listed in the table: Synthesis Process ren 1/2N (g) + 3/2H,g) 2NH,(g) AH AS (kJ mol) K'mol") -45.9 -99.1 1. Justify the signs of AHºrn and Asº ran based on the analysis of the nature of reactants and products. 2. Express the equilibrium constant for the process Kp in terms of the pressures of reactants and products. Calculate its value under standard conditions. 3. Build a qualitative graph for AGºran (T) as a function of temperature T and discuss whether the reaction will be favored at low or high temperatures. Thermodynamics versus Kinetics: The activation energy for the synthesis of NH3(g) from H2(g) and N2(g) in the absence of catalyst is high, E, = 325 kJ/mol. The rate of the reaction may be increased by carrying out the synthesis at a high temperature (-500 °C). 4. Build a potential energy diagram for the synthesis of ammonia. 5 Determine how many times faster the reaction is at 500 °C than at 25°C 6 Determine how many times smaller Ko is at 500 C than at 25 C.
