Labzone Build Inquiry Fill one plastic cup with cold tap water and the other plastic cup with hot tap water Predict whether or not the antacid tablet will react faster in hot water or cold water Test your hypothesis How did the two reactions occur.?
Notes on Controlling Chemical Reactions How does temperature affect a chemical reaction? Answer: higher temperatures provide the activation energy needed for a chemical reaction to occur. 2) What does concentration mean? Answer: The Amount of a Substance in a Given Volume 3) How might our normal body temperature be related to our dependence on catalysts? Answer: Our body temperature is too low for many chemical reactions to take place without the help of catalysts.
