Two Solutions,initially at 24

question 103

Multiple Choice

Two solutions,initially at 24.69°C,are mixed in a coffee cup calorimeter.When a 200.0 mL volume of 0.100 M AgNO₃ solution is mixed with a 100.0 mL sample of 0.100 M NaCl solution,the temperature in the calorimeter rises to 25.16°C.Determine the DH°_rxn,in units of kJ/mol AgCl.Assume that the density and heat capacity of the solutions is the same as that of water.Hint: Write a balanced reaction for the process.

• A) -32 kJ/mol AgCl
• B) -78 kJ/mol AgCl
• C) -59 kJ/mol AgCl
• D) -25 kJ/mol AgCl
• E) -62 kJ/mol AgCl
