Question
In a constant-pressure calorimetry experiment, Hayoung mixed 100.0 mL of 1.00 M H2C>O4 solution and 100.0 mL of 1.00
M KOH solution. The initial temperature of both solutions is 20.00°C. After a while, she observed that the temperature of
the calorimeter had reached a constant value at 26.61°C. Calculate the enthalpy of neutralization for the following
reaction:
H2C204(aq) + 2KOH(aq) – K2C204(aq) + 2H20
Assume that solution has the same specific heat capacity and density as water, and the calorimeter absorbed a negligible
amount of heat.
A-27.7 kj mol-1
B -111 kj mol-1
