The Enthalpy Change When a Strong Acid Is Neutralized by Strong

question 16

Multiple Choice

The enthalpy change when a strong acid is neutralized by strong base is -56.1 kJ/mol. If 135 mL of 0.450 M HI at 23.15°C is mixed with 145 mL of 0.500 M NaOH, also at 23.15°C, what will be the maximum temperature reached by the resulting solution? (Assume that there is no heat loss to the container, that the specific heat of the final solution is 4.18 J/g·°C, and that the density of the final solution is that of water.)

• A)26.06°C
• B)29.19°C
• C)32.35°C
• D)20.24°C
• E)36.57°C
