- Acetaldehyde (CH3CHO) is an important chemical both industrially and biologically. For instance, it is a (somewhat toxic) intermediate in the body's metabolism of ethanol into acetic acid, and thus is possibly implicated in the "hungover" symptoms of someone who has had too much to drink the night before. In aqueous solution, it establishes an equilibrium with a hydrated form, shown below. CH3CHO (aq) + H2O (l) <--> CH3CH(OH)2 (aq) You start with an aqueous sample, already at equilibrium, with the CH3CH(OH)2 (the hydrated form) at a concentration of 2.60 M. You have no information about how much, if any, of the anhydrous form (CH3CHO) is initially in the flask. If you add 2.0 M of CH3CHO to the reaction flask, and as the equilibrium is being restored the amount of CH3CH(OH)2 changes by 1.13 M, what is the final amount of CH3CHO?arrow_forwardWhich of the following is the equilibrium constant expression for the reaction?

Q = 0.727, therefore the reaction is at equilibrium and will not proceed in either direction. Q = 1.42, therefore, the reaction will shift to make more 1-butene to reach equilibrium. 1-butene isobutene Q = 1.42, therefore the reaction will shift to make more isobutene to reach equilibrium. The equilibria were studied in the gas phase at high temperatures (Petroleum Chemistry, 2001, 41, 144-148). The equilibrium constant for the isomerization of 1- butene to isobutene at 644 °C is K = 0.73. O Q= 0.705, therefore, the reaction will shift to make more 1-butene to reach equilibrium. O Q= 0.705, therefore, the reaction will shift to make more isobutene to reach equilibrium. A mixture of 1-butene (P = 1.94 bar) and isobutene (P = 2.75 bar) were placed in a vessel at 644 °C and were allowed to come to equilibrium.…arrow_forward
