Explain the changes made to the equilibrium mixture and their effects on the yield of ammonia.

Hey Omo😍💥, good to see you again. Here are the changes made to the equilibrium mixture and which led to a higher yield of ammonia: 7.4.1 At t_1, the concentrations of all species show an instantaneous change (N_2 and H_2 increase, NH_3 decreases), followed by a gradual shift. This indicates a change in pressure. Since the concentrations of all species increase initially, it means the volume decreased, leading to an increase in pressure. The equilibrium then shifts to the right (towards fewer moles of gas), increasing NH_3 and decreasing N_2 and H_2. Change: Increase in pressure 7.4.2 At t_2, the concentration of N_2 shows an instantaneous increase, while H_2 and NH_3 concentrations do not change instantly. This indicates the addition of N_2. The equilibrium then shifts to the right to consume the added N_2, increasing NH_3 and decreasing H_2 and N_2. Change: Addition of N_2 7.4.3 At t_3, all concentrations change gradually without any instantaneous jumps. The concentration of NH_3 decreases, while N_2 and H_2 increase. This indicates a shift to the left. Since the forward reaction is exothermic ( H < 0), an increase in temperature favors the endothermic reverse reaction. Change: Increase in temperature 7.5 A higher yield of ammonia means the equilibrium shifts to the right, increasing the concentration of NH_3. • At t_1, increasing pressure shifts the equilibrium to the right (fewer moles of gas), leading to a higher yield of NH_3. • At t_2, adding N_2 (a reactant) shifts the equilibrium to the right, leading to a higher yield of NH_3. • At t_3, increasing temperature shifts the equilibrium to the left (endothermic reverse reaction), leading to a lower yield of NH_3. Therefore, the changes made at t_1 and t_2 led to a higher yield of ammonia. Answer: t_1 and t_2 Send me the next one 📸
