Question

Please show the work of the calculation

2. Calculate the heat loss or heat gain of the 3 solution mixtures (on). Then calculate the AH for each reaction. Write the calculations on a sheet of paper showing all of your work. Take a photo of your work for each reaction and upload the images into Photo 1, Photo 2, and Photo 3 BUIE ETT 22 Words HCI & NaOH.........> NaCl + H20 = 461 NHACI NaOHNH3 NaCl + H20213 NH3 + HC ....

Answer 1

.Use Hess’s Law to determine ΔH for the first 2 reactions and then add them together to determine ΔH for the third reaction:

NH3+ HCl $\rightleftharpoons$ NH4Cl.

Reaction 1= 2.31kj

Reaction 2= 0.11 kj

Reaction 3= 2.2 kj

Compare the results of question “C” with the experimental results of the reaction:

NH3+ HCl $\rightleftharpoons$ NH4Cl (calculate the percent difference). There is a 0.1 kj differenceE.

Use the thermodynamic quantities given below to calculate the theoretical ΔHfor thisreaction: NH3+ HCl $\rightleftharpoons$ NH4Cl. ΔH°f

for NH3(aq) = - 80.29 kJ/molΔH°f

for HCl (aq) = - 167.2 kJ/molΔH°f

for NH4+(aq) = - 132.5 kJ/molΔH°f

for Cl-(aq) = - 167.2 kJ/mol

NH3 + HCl $\rightleftharpoons$ NH4Cl ΔH = -52.21 KJF.
