A 350.0 mL sample of compound A in water at 0.200 M is mixed with a 200.0 mL sample of compound B in water at 0.450 M in a calorimeter. If both aqueous solutions were initially at 34.0°C and the temperature of the resulting solution of A and B was recorded as 39.0°C, determine the AH°rxn in units of kJ per mol of compound A for the reaction. Assume the complete reaction of compound A and a specific heat capacity of 4.18 J/g°C and density of 1.00 g/mL for all solutions.

Question
Transcribed Image Text:A 350.0 mL sample of compound A in water at
0.200 M is mixed with a 200.0 mL sample of
compound B in water at 0.450 M in a calorimeter.
If both aqueous solutions were initially at 34.0°C
and the temperature of the resulting solution of A
and B was recorded as 39.0°C, determine the
AH°rxn in units of kJ per mol of compound A for
the reaction. Assume the complete reaction of
compound A and a specific heat capacity of 4.18
J/g°C and density of 1.00 g/mL for all solutions.
