Why do you get a better reaction with warm or hot vinegar and baking soda?

When baking soda (sodium bicarbonate) and vinegar (acetic acid) are mixed, they undergo a chemical reaction that produces carbon dioxide gas. This reaction is exothermic, meaning it releases heat. The heat produced by the reaction causes the mixture to fizz and bubble.

The rate of this reaction is affected by several factors, including temperature. As the temperature of the reactants increases, the rate of the reaction also increases. This is because higher temperatures provide more energy to the reactants, which allows them to overcome the activation energy barrier for the reaction.

Therefore, you get a better reaction with warm or hot vinegar and baking soda because the higher temperature speeds up the reaction rate. This produces more carbon dioxide gas and a more vigorous fizz and bubble reaction.
