= Kinetics and Equilibrium Using an equilibrium constant to predict the direction of spontaneous... chemical engineer is studying the following reaction: HCH₂ CO₂(aq) + CH³NH₂(aq) → CH³CO₂(aq)+CH₂NH₂(aq) At the temperature the engineer picks, the equilibrium constant K for this reaction is 2.0. The engineer charges ("fills") four reaction vessels with acetic acid and methylamine, 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. reaction vessel A B Explanation compound HCH₂ CO₂ CH,NH, CH,CO, CH₂NH3 HCH₂ CO₂ CH,NH, CH,CO, CH₂NH3 HCH, CO2 CH,NH, CH,CO, CHÍNH Check + + + concentration 0.50 M 0.26 M 1.22 M 1.08 M 1.02 M 0.78 M 0.70 M 0.56 M 1.00 M 0.68 M 1.26 M 1.08 M expected change in concentration increase ↑ increase ↑ increase increase ↑ increase ↑ increase…
