Question

1. Construct two plots with the following data

a. plot 1: ΔT (^oC) (y-axis) vs. moles of HCl (x-axis)

b. plot 2: q_rxn (yaxis) vs. moles of HCl (x-axis). (Use equations 3 and 2 from the lab handout to calculate the y-axis values and 100.0 g as the mass of the solution.)

2. The complete neutralization of 0.0482 moles of a monoprotic acid (HA) with excess NaOH evolves 2.58 kJ of heat. What is the molar heat of neutralization of the acid with NaOH from this data.

3. A student collected the following data while determining the molar heat of neutralization of a monoprotic acid, HA with NaOH. Calculate the molar heat of neutralization of this acid with NaOH. Assume that the specific heats of the solutions are the same as water.

Moles of HCI 0.69 0.82 0.96 1.10 1.23 1.37 1.51 1.55 1.60 1.70 AT/oC 3.7 4.0 4.6 5.7 6.3 6.3 6.4 6.5 6.4 6.4 Temperature of HA and NaOH before mixing 23.7 oC 1.10 M 0.960 M 50.0 ml 50.0 mL 28.7 oC 6.5 J/oC Concentration of the acid, HA Concentration of the NaOH Volume of the acid, HA used Volume of the base, NaOH used lemperature of the calorimeter and mixture at time Heat capacity of calorimeter 0
