Does the reaction take longer if more vinegar is added to the baking soda?

write what you think (hypothesis)

I don't think the reaction would take longer.  If anything the reaction would get faster since you are making it so that more vinegar can react with the baking soda at the same time.

I hope this helps.  Let me know in the comment if anything is unclear or if you want me to add more explanation to my answer.
