The Enthalpy Change When a Strong Acid Is Neutralized by Strong

question 103

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 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)18.20°C
• B)24.53°C
• C)101.8°C
• D)24.40°C
• E)34.25°C
