will the temperature of vinegar effect its reaction to baking Soda?[/code]

AE3BOOMER,
This sounds suspiciously like a homework problem. ScienceBuddies doesn' provide homework help; we help students prepare science fair projects.
If this question really is related to your science fair project, can you please provide some background (what is your question, hypothesis, etc.). The more information you provide us about your project, the better we can help you!

All the best,

You can learn a lot of chemistry and thermodynamics from a simple vinegar / baking soda reaction with lots of different variations. Great basis for a variety of science fair projects.
Did you try something like putting "Vinegar Baking Soda reaction time vs temperature" into a search engine?
I tried it with google and got http://www.apple-cider-vinegar-benefits ... negar.html as the second hit.
The internal link to "Analyzing the reaction's change in temperature, pH and mass." provides a chart that plots the reaction temperature vs time and a discussion of the curve and why this indicates this reaction is endothermic.
Try looking up endothermic reactions to find out some more.
If you look closely at the shape of the Temperature curve, the change starts out slowly as the reagents meet and then drops quickly before slowing down.
If I had to guess (form a hypothesis) of how a higher starting temperature (all other things being equal ) would affect this curve, I would expect a similar shaped curve with same total change in temperature but with a steeper slope after the initial startup and a flatter slope approaching completion. But this would just be my guess. Unless somebody does this exact experiment, knowbody knows if I'm even close to being a good guesser.
Try guessing at what difference this might have on the total reaction time.
There is a lot of physics going on in this chemistry experiment. The balloon collecting the CO2 is increasing the vapor pressure as it fills which increases the solubility of CO2 in the liquid which decreases the rate of temperature loss caused by the gas evaporating.
Change the experiment by leaving off the balloon and letting the CO2 escape and you have a whole different experiment.
Try looking up heat of vaporization and Reynolds equations for some information on the thermodynamics involved.
