Acetic acid and water react to from hydronium cation and acetate anion, like this: HCH3CO2 (aq) + H2O (I) >H3O +(aq) + Ch3CO2 -(aq)
Imagine 226. mmol of CH3CO2- are added to a flask containing a mixture of HCH3CO2, H2O, H3O + and CH3CO2- at equilibrium, and then answer the following questions.
1. What is the rate of the forward reaction before any HCH3CO2 has been removed from the flask?
i. Greater than zero, but less than the rate of the reverse reaction.
ii. Greater than zero, and equal to the rate of the reverse reaction.
iii. Greater than zero, and greater than the rate of the reverse reaction.
iv. Greater than zero, but less than the rate of the reverse reaction.
v. Zero
2. What is the rate of the forward reaction just after the HCH3CO2 has been removed from the flask?
i. Greater than zero, and equal to the rate of the reverse reaction.
ii. Greater than zero, and greater than the rate of the reverse reaction.
iii. Greater than zero, but less than the rate of the reverse reaction.
iv. Zero
3. What is the rate of the forward reaction when the system has again reached equilibrium?
i. Greater than zero, and equal to the rate of the reverse reaction.
ii. Greater than zero, and greater than the rate of the reverse reaction.
iii. Zero
