I wanted to ask, let say:-
Situation A
1M of Acetic Acid + x amount of Sodium Bicarbonate(Baking Soda)
Situation B
3M of Acetic Acid + x amount of Sodium Bicarbonate(Baking Soda)
From the above situations, 2 different concentration of a same acid, one is triple(Yes, to be exact is TRIPLE) the concentration of the other one and mix with a SAME amount of Sodium Bicarbonate, will reaction make a big difference in terms of :-
1. The amount of CO2 gas produced
2. (Important question)The pressure produced if both reactions are being carried out in a bottle stucked with a rubber stopper.
3. The pressure produce to move an object from the nozzle(To be exact, 1st..the bottle is shaken to enable the reaction take place, the nozzle is still CLOSE(to build up the pressure), after around 10-15 seconds, the nozzle is open, will it create a big difference in terms of pressure of CO2 gas pushes out through the nozzle if using 1M and 3M of Acetic Acid and will it a ble to move a model car with load of 100ml of water + the bottle on the car?)
Thanks
I am not sure if the reaction is reversible or not because acetic acid is a weak acid and it doesn't ionised completely. But lets assume the reaction is not reversible.Situation A
1M of Acetic Acid + x amount of Sodium Bicarbonate(Baking Soda)
Situation B
3M of Acetic Acid + x amount of Sodium Bicarbonate(Baking Soda)
From the above situations, 2 different concentration of a same acid, one is triple(Yes, to be exact is TRIPLE) the concentration of the other one and mix with a SAME amount of Sodium Bicarbonate, will reaction make a big difference in terms of :-

We still need to know what is the limiting factor of this reaction. If acetic acid as abundant and the end product of CO2 is not affected by the concentration of acetic acid. However, if baking soda is abundant, then the more concentrated the acid, the more CO2 is produced.
Pressure produced is directly proportionate to the amount of CO2 produced
