A chemical engineer is studying the following reaction:CH3CH2NH2(aq) + HCl(aq) → Cl˜¯(aq)+CH¸CH₂NH(aq)At the temperature the engineer picks, the equilibrium constant K for this reaction is 2.1.The engineer charges ("fills") four reaction vessels with ethylamine and hydrogen chloride, and lets the reaction begin. She then measures the composition ofthe 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. reactionvesselcompound concentrationexpected change in concentrationCH2CH2NH₂0.77 M○ ↑ increase○↓ decrease(no change)HCl0.78 M↑ increase○ decrease○ (no change)ACl1.31 M↑ increaseOdecreaseCH2CH2NH0.96 M○ ↑ increase○ decreaseCH2CH2NH₂0.85 M○ ↑ increaseO↓ decreaseHCl0.86 M○ ↑ increase○ ↓ decreaseBCl0.69 M↑ increaseOdecreaseCH3CH2NH30.43 M○ ↑ increaseO↓ decreaseCH3CH2NH₂0.29 M↑ increaseOdecrease(no change)○ (no change)(no change)○ (no change)(no change)○ (no change)○ (no change)HCl0.30 M↑ increaseOdecrease(no change)CCl1.25 M↑ increaseOdecrease○ (no change)CH,CH,NH,0.99 M○ ↑ increaseO↓ decrease○ (no change)
