Practice Questions: Endothermic and Exothermic Reactions
   This worksheet is also available in the following formats:  Word | RTF | PDF
1. Identify each of the following reactions as exothermic or endothermic.
 
CH4(s) + 2O2(g) → CO2(g) + 2H2O(l) ΔH° = -890 kJ
2HCl(g) → H2(g) + Cl2(g) ΔH° = 185 kJ
4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(l) ΔH° = -1169 kJ
2. When potassium nitrate dissolves in water, the beaker containing the solution gets cooler. Is dissolving this salt an exothermic or an endothermic process?
