My experiment involves the reaction between sodium bicarbonate and acetic acid. I'll be changing the temperature between each trial and measuring the change in pressure by the gas produced. From here I hope to determine the rate expression, rate constant, activation energy then finally produce an Arrhenius plot.
My question is since this reaction is endothermic, how do I account for the change in temperature as the reaction proceeds? I also can't seem to find any published literature value for this reaction's activation energy or enthalpy change, and would love it if someone pointed out a database or something similar.
