Predicting relative forward and reverse rates of reaction in a dynamic... Acetic acid and ethanol react to form ethyl acetate and water, like this: HCH3CO2(aq)+C₂H₂OH(aq) →C₂H₂CO₂CH3(aq)+H2O(l) Imagine 87. mmol of HCH3CO2 are added to a flask containing a mixture of HCH¸CO₂, C₂H₂OH, C₂H¸CO₂CH3 and H₂O at equilibrium, and then answer the following questions. What is the rate of the forward reaction before any HCH3CO2 has been added to the flask? What is the rate of the forward reaction just after the HCH3CO2 has been added to the flask? What is the rate of the forward reaction when the system has again reached equilibrium? How much more HCH3CO2 is in the flask when the system has again reached equilibrium? Zero. Greater than zero, but less than the rate of the reverse reaction. Greater than zero, and equal to the rate of the reverse reaction. Greater than zero, and greater than the rate of the reverse reaction. Zero. Greater than zero, but less than the rate of the reverse reaction.…
