Given the data, calculate the enthalpy change per mole of NaOH dissolved and explain whether the process is exothermic or endothermic. Approach: Step 1: Identify Known Data - Mass of NaOH sample - Temperature change (ΔT) - Specific heat capacity of water - Final volume of solution Step 2: Calculate Heat Absorbed or Released (q) - Use the calorimetry formula: q = mcΔT where m = mass of water, c = specific heat capacity, ΔT = temperature change Step 3: Convert to Moles of NaOH - Calculate moles of NaOH using molar mass moles = mass of NaOH / molar mass Step 4: Determine Enthalpy Change per Mole - ΔH = q / moles 4 Step 5: Interpret the Results - If q is negative, the process releases heat (exothermic) - If q is positive, it absorbs heat (endothermic) Sample Calculation: - Suppose 5.00 g of NaOH dissolves, ΔT = 10°C, 100 g of water, c = 4.18 J/g·°C - q = (100 g)(4.18 J/g·°C)(10°C) = 4180 J - Moles of NaOH = 5.00 g / 40.00 g/mol = 0.125 mol - ΔH = 4180 J / 0.125 mol = 33,440 J/mol or 33.44 kJ/mol Conclusion: Since heat is released, the dissolution process is exothermic, with an enthalpy change of approximately -33.44 kJ/mol. --- Common Pitfalls and Tips for Success Misreading Data: Always verify units and data accuracy before calculations. Ignoring Significant Figures: Use appropriate precision for final answers. Overlooking Part C or D of Questions: Address all components thoroughly. Neglecting Conceptual Justification: Support calculations with proper explanations. Running Out of Time: Practice timed exams to improve efficiency. --- Additional Resources for 1996 AP Chem FRQ Preparation - Review official College Board past exam questions and scoring guidelines - Practice with released free-response questions from previous years - Utilize AP Chemistry prep books with detailed solutions - Join study groups to discuss challenging problems - Attend review sessions focusing on common question types --- Conclusion Understanding and mastering the 1996 AP Chem FRQ requires a solid grasp of core chemistry concepts, strategic problem-solving skills, and clear communication.
