Answer 2

Factors Affecting the Yield of Ammonia in the Synthesis Reaction

To increase the yield of ammonia in the synthesis reaction from the simple substances N2(g) and 3H2(g) to 2NH3(g), several factors can be adjusted to favor the production of more ammonia. These factors include:

1. Pressure: - Increasing the pressure can favor the formation of ammonia, as per Le Chatelier's principle. - Higher pressure helps to shift the equilibrium towards the side with fewer moles of gas, which in this case is the side with ammonia. - Source: 2. Temperature: - Lowering the temperature can increase the yield of ammonia. - The forward reaction is exothermic, so lowering the temperature will favor the exothermic reaction, resulting in higher ammonia yield. - Source: 3. Concentration of Reactants: - Increasing the concentration of the reactants (N2 and H2) can help increase the yield of ammonia. - This change can help shift the equilibrium towards the formation of more ammonia. - Source: 4. Catalyst: - Using an appropriate catalyst, such as iron, can increase the rate of the reaction and, consequently, the yield of ammonia. - The catalyst provides an alternative reaction pathway with lower activation energy, allowing more ammonia to be produced in a given time. - Source: By adjusting these factors, it is possible to achieve a higher yield of ammonia in the synthesis reaction from the simple substances N2(g) and 3H2(g) to 2NH3(g).
