The Enthalpy Change When a Strong Acid Is Neutralized by Strong

question 108

Multiple Choice

The enthalpy change when a strong acid is neutralized by strong base is -56.1 kJ/mol. If 12.0 mL of 6.00 M HBr at 21.30°C is mixed with 300.mL of 0.250 M NaOH, also at 21.30°C, what will 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)18.20°C
• B)24.53°C
• C)101.8°C
• D)24.40°C
• E)34.25°C
