A student performed a chemical reaction similar to the one in Part A using an Alka-Seltzer (MM = 456.29 g/mol) tablet that has a mass of 3.09 g in 21.50 mL of room temperature water. 1. Assuming that the entire tablet reacts in 80.16 seconds, calculate the reaction rate (M/s). 2. Explain how the rate of the reaction would change if the water were boiling? 3. Explain how the rate of the reaction would change if the tablet had been pulverized? 4. Explain if there is there a catalyst present in this system.
