A chemical engineer is studying the following reaction: CH3CH₂NH₂(aq) + HCl(aq) → At the temperature the engineer picks, the equilibrium constant K for this reaction is 2.0. с The engineer charges ("fills") four reaction vessels with ethylamine and hydrogen chloride, 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 B C compound CH,CH,NH, H Cl Cl CH₂CH₂NH3 CH,CH,NH, H Cl Cl CH,CH,NH, CH,CH,NH, H Cl Cl Cl¯(aq)+CH₂CH₂NH²(aq) CH,CH,NH, concentration 0.22 M 0.29 M 0.91 M 1.23 M 0.71 M 0.80 M 0.86 M 1.30 M 0.85 M 0.92 M 0.28 M 0.60 M expected change in concentration ↑ increase ↑ increase ↑ increase ↑ increase increase ↑ increase increase ↑ increase ↑ increase ↑ increase ↑ increase ↑ increase ↓ decrease ↓ decrease ↓ decrease decrease ↓ decrease…
