A chemical engineer is studying the following reaction:
HCH3O2(aq) + CH3NH2(aq) → CH3CO^-(aq) + CH3NH^+(aq)
At the temperature the engineer picks, the equilibrium constant Kc for this reaction is 1.7.
The engineer charges ("fills") four reaction vessel with acetic acid and methylamine, 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 engineer should expect next time she measures the compositions.
