Yvette conducted an eperiment investigating the effects of temperature on chemical
reaction time. She dropped an Alka Seltzer tablet in water of different temperatures and
measured the time it took for the reaction to complete. She hypothesized that the Alka
Seltzer tablet would react faster in warmer water.
1. Was Yvette's hypothesis correct? Explain your answer.
2. If Yvette dropped an Alka Seltzer tablet in water at 35*C, how long could she expect the reaction to take? Explain your answer.
3. Which reaction time is not consistent with the rest of the data table? What should its value be? What could have caused this inconsistency? Explain your answer.
