Multiple Choice
Two solutions,initially at 24.60°C,are mixed in a coffee cup calorimeter.When a 100.0 mL volume of 0.100 M AgNO3 solution is mixed with a 100.0 mL sample of 0.200 M NaCl solution,the temperature in the calorimeter rises to 25.30°C.Determine the DH°rxn for the reaction as written below.Assume that the density and heat capacity of the solutions is the same as that of water.
NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq) DH°rxn = ?
A) -35 kJ
B) -59 kJ
C) -250 kJ
D) -16 kJ
