When heated above 200°C, sodium bicarbonate decomposes quickly to form sodium
carbonate, water, and carbon dioxide. Find the AH for the reaction, and classify the reaction
as endothermic or exothermic.
2NaHCO3 (s) → Na, CO3 (s) + H20 (1) + CO2 (9)
21-948 kJ/mol) → (-1311 kJ/mol) + (-286 kJ/mol) + (-394 kJ/mol)
AH = {AH, (products) - EAH, (reactants)
