Question
10. The enthalpy change for the reaction: H+(aq) + OH-(aq) → H2O (l) ΔHorxn =-57.6 kJ/mol. If 161.4 mL of 0.52 M H3PO4 at 24.17°C is mixed with 169.1 mL of 0.56 M Ba(OH)2 at 24.17°C, what is the maximum temperature reached by the resulting solution if the heat capacity of the calorimeter is 435.6 J/K? 11. A 114.06 mL sample of 0.245 M aqueous hydrochloric acid is added to 122.18 mL of 0.172 M aqueous ammonia in a calorimeter whose heat capacity (excluding any water) is 498.075 J/K. The following reaction occurs when the two solutions are mixed. HCl(aq) + NH3(aq) → NH4Cl(aq) The temperature increase is 2.03°C. Calculate ΔHorxn. Answer=____________________kJ/mol Please answer 10 and 11
