A chemical engineer is studying the following reaction: N₂(0)+ 3H₂(0)2NH,(0) At the temperature the engineer picks, the equilibrium constant K, for this reaction is 0.0026. The engineer charges ("fills") three reaction vessels with nitrogen and hydrogen, and lets the reaction begin. She then measures the composition of the mixture inside each vessel from time to time. Her first set of measurements are shown in the table below. Predict the changes in the compositions the engineer should expect next time she measures the compositions. reaction vessel compound N₂ H₂ NH, N₂ 1₂ NH, N₁ H₂ NH, pressure 47.06 am 25.70 atm 41.92 alm 46.75 atm 24.76 m 42.55 atm 46:40 am 23.71 m 43.25 am expected change in pressure 1 increase O 1 increase O decrease decrease 01 increase 01 increase decrease O decrease increase O decrease 1 increase Oi decrease DT increase of increase of increase O decrease decreases decrease X (no change) (no change) (no change) (no change) (no change) (no change) (no change) (no change) (no change). 5

Question
A chemical engineer is studying the following reaction: N₂(9)+ 3H₂(g) → 2NH₂(g) At the temperature the engineer picks, the equilibrium constant K, for this reaction is 0.0026. The engineer charges ("fills") three reaction vessels with nitrogen and hydrogen, and lets the reaction begin. She then measures the composition of the mixture inside each vessel from time to time. Her first set of measurements are shown in the table below. Predict the changes in the compositions the engineer should expect next time she measures the compositions. reaction vessel A compound N₂ H₂ NH, N₂ H₂ NH, N₂ H₂ NH, pressure 47.06 atm 25,70 atm 41.92 atm 46.75 atm 24,76 m 42.55 atm 46.40 atm 23,71 m 43.25 am expected change in pressure 1 increase O decrease 1 increase 01 increase O increase O decrease OT increase 1 increase OT increase of increase O decrease O increase decrease decrease O decrease O decrease decrease decrease X (no change) (no change) (no change) (no change) (no change) (no change) (no change) (no change) (no change) 5
