A chemical engineer is studying the following reaction: N₂(g) + 3H₂(g) → 2NH₂(9) At the temperature the engineer picks, the equilibrium constant K, for this reaction is 0.0043. The engineer charges ("fills") three reaction vessels with nitrogen and hydrogen, and lets the reaction begin. He then. measures the composition of the mixture inside each vessel from time to time. His first set of measurements are shown i the table below.

A chemical engineer is studying the following reaction:
N₂(9)+3H₂(g) 2 NH₂(g)
-
At the temperature the engineer picks, the equilibrium constant K, for this reaction is 0.0043.
The engineer charges ("fills") three reaction vessels with nitrogen and hydrogen, and lets the reaction begin. He then
measures the composition of the mixture inside each vessel from time to time. His first set of measurements are shown in
the table below.
Predict the changes in the compositions the engineer should expect next time he measures the compositions.
