(multi step problem!). activation energy determination 19 C: i need help calculating Ea

and answering the questions

Volume of balloon and water vapor Volume of water in graduated cylinder 62.8 mL Volume of water and balloon in graduated cylinder 69.8 Volume of balloon and water vapor 7 mL ml 69.8-62.8 Station 1 (-0 C) Temperature 0.3 "C Temperature 273.45 K. 1/Temperature 0.00 310 1/K Volume of water in graduated cylinder 62.8 ml Volume of water and balloon in graduated cylinder_17 Volume of balloon and gas in the balloon 18.6 mL Volume of Co, 18.6 In(volume of coa) in 118.6)- 2.92 mL mL 1. Comment on the magnitude of the value of the activation energy that you found. Is this number reasonable? Explain your rationale for your conclusion 2. Why does the experiment not determine the activation energy for the reaction of citric acid and sodium bicarbonate? (Provide at least two reasons)
