Of the answers listed I would choose decomposition. I think oxidation is a better term.
I have problems with the second question. What are you calling the reactant? First BOTH H2O and ALKASELTZER are reactants. So temperature affects the solvent (H2O) but surface area affects the alkaseltzer tablet.
Determine the type of reaction: H2O + C16H17NaO14 = C02 + H20 + C2H3NaO3
Single replacement
Synthesis
Decomposition
Double Replacement
Which factor is affecting the rate at which H20 is reacting w/Alka-Seltzer?
Size or surface area of reactant
Concentration of reactant
Temperature of reactant THIS ONE
