Transcribed Image Text: Acetic acid and water react to form hydronium cation and acetate anion, like this:
HCH,CO,(aq)+H,O() → H,0″(aq)+CH,CO,(aq)
Imagine 240. mmol of HCH,CO, are removed from a flask containing a mixture of HCH,CO,, H,O, H,0¯ and CH,CO, at equilibrium, and then answer the
following questions.
O Zero.
What is the rate of the forward
reaction before any HCH,CO, has
O Greater than zero, but less than the rate of the reverse reaction.
O Greater than zero, and equal to the rate of the reverse reaction.
O Greater than zero, and greater than the rate of the reverse reaction.
O Zero.
What is the rate of the forward
reaction just after the HCH-Co, has
O Greater than zero, but less than the rate of the reverse reaction.
O Greater than zero, and equal to the rate of the reverse reaction.
O Greater than zero, and greater than the rate of the reverse reaction.
O Zero.
What is the rate of the forward
reaction when the system has again
reached equilibrium?
O Greater than zero, but less than the rate of the reverse reaction.
O Greater than zero, and equal to the rate of the reverse reaction.
O Greater than zero, and greater than the rate of the reverse reaction.
O None.
How much less HCH CO, is in the
flask when the system has again
reached equilibrium?
O Some, but less than 240. mmol.
O 240. mmol.
O More than 240. mmol.
