A chemical engineer is studying the following reaction: HCH,CO,(aq)+CH,NH,(aq) → CH3CO,(aq)+CH3NH;(aq) At the temperature the engineer picks, the equilibrium constant K, for this reaction is 0.93. 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 compound concentration expected change in concentration vessel HCH,CO, 0.94 M t increase OI decrease (no change) CH,NH, 1.01 M t increase OI decrease O (no change) A CH,CO, 0.56 M O t increase OI decrease O (no change) CH,NH, 0.22 M O t increase OI decrease (no change) HCH,CO, 1.05 M t increase I decrease O (no change) CH;NH, 1.12 M O t increase OI decrease O (no change) CH,Co, O t increase 0.45 M I decrease (no change) CH.NH 0.11 M t increase OI decrease O (no change)

Methanol, a common laboratory solvent, poses a threat of blindness or death if consumed in sufficient amounts. Once in the body, the substance is oxidized to produce formaldehyde (embalming fluid) and eventually formic acid. Both of these substances are also toxic in varying levels. The equilibrium between methanol and formaldehyde can be described as follows: CH3OH(aq)H2CO(aq)+H2(aq) Assuming the value of K for this reaction is 3.7 1010, what are the equilibrium concentrations of each species if you start with a 1.24 M solution of methanol? What will happen to the concentration of methanol as the formaldehyde is further converted to formic acid?
