chemical engineer is studying the following reaction: HCH₂CO₂(aq) + CH3NH₂(aq) → CH₂CO₂(aq)+CH₂NH3(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 B с compound HCH,CO₂ CHÍNH, CH,CO.
