Question
Imagine 159. mmol of HCH,CO2 are added to a flask containing a mature of HCH,CO2. C.H OH C2H,CO,CH, and H,O at equibrium, and then a moxture of O Greater than zero, but less than the rate of the reverse reaction Greater than zero, and equal to the rate of the reverse reaction. What is the rate of the forward reaction Just after the HCH CO2 has been added to the flask? O Greater than zero, but less than the rate of the reverse reaction. Greater than zero, and equal to the rate of the reverse reaction What is the rate of the forward O Greater than zero, but less than the rate of the reverse reaction. Greater than zero, and equal to the rate of the reverse reaction flask when theExplanation / Answer
(1) before addition of HCH3CO2 , reaction was at equlibrium so rate of forward reaction
Greater than 0, and equal to rate of reverse reaction (because system was at equlibrium).
(2) just after addition of HCH3CO2 , reaction will go in forward direction to achieve equlibrium so rate fo forward reaction
Greater than 0, and greater than rate of reverse reaction.
(3) when system reach at equlibrium again, rate of forward reaction
Greater than 0, and equal to reverse reaction rate. (because syatem achieve equlibrium again)
(4) on reaching equlibrium again, some HCH3CO2 converted into product so amount of HCH3CO2 after new equlibrium
some but less than 159 mmol.
