Two Solutions, Initially at 24

question 117

Multiple Choice

Two solutions, initially at 24.60 °C, are mixed in a coffee cup calorimeter (C_cal = 15.5 J °C^-1) . When a 100.0 mL volume of 0.100 mol L^-1 AgNO₃ solution is mixed with a 100.0 mL sample of 0.200 mol L^-1 NaCl solution, the temperature in the calorimeter rises to 25.30 °C. Determine the Δ_rH° for the reaction as written below. Assume that the density and specific heat capacity of the solutions is the same as that of water. NaCl(aq) + AgNO₃(aq) → AgCl(s) + NaNO₃(aq) Δ_rH° = ?

• A) -35 kJ mol^-1
• B) -59 kJ mol^-1
• C) -250 kJ mol^-1
• D) -16 kJ mol^-1
• E) -140 kJ mol^-1
