Question 1

Calculate the energy change for the formation of LiCl(s) from its elements in their standard states and the following tabulated information:

Li(s) + 1/2 Cl2(g) → LiCl(s)?
Li+(g) + Cl-(g) → LiCl(s)-853 kJ/mol
Li(s) → Li(g)+159.4 kJ/mol
1/2 Cl2(g) → Cl(g)+121.7 kJ/mol
Cl(g) + e- → Cl-(g)-348.6 kJ/mol
Li(g) → Li+(g) + e-+520.2 kJ/mol

◦ -400.3 kJ/mol
◦ +1305.7 kJ/mol
◦ -627.2 kJ/mol
◦ +296.9 kJ/mol

Question 2

Calculate the lattice energy for NaCl(s) using a Born-Haber cycle and the following information:

NaCl(s) → Na+(g) + Cl-(g)?
Na(s) + 1/2 Cl2(g) → NaCl(s)-411.0 kJ/mol
Na(s) → Na(g)+107.3 kJ/mol
Na(g) → Na+(g) + e-+495.8 kJ/mol
1/2 Cl2(g) → Cl(g)+121.7 kJ/mol
Cl(g) + e- → Cl-(g)-348.6 kJ/mol

◦ +787.2 kJ/mol
◦ +34.8 kJ/mol
◦ +1512 kJ/mol
◦ +690.3 kJ/mol

Wow, this really help

 

Did you know?

Studies show that systolic blood pressure can be significantly lowered by taking statins. In fact, the higher the patient's baseline blood pressure, the greater the effect of statins on his or her blood pressure.

Did you know?

GI conditions that will keep you out of the U.S. armed services include ulcers, varices, fistulas, esophagitis, gastritis, congenital abnormalities, inflammatory bowel disease, enteritis, colitis, proctitis, duodenal diverticula, malabsorption syndromes, hepatitis, cirrhosis, cysts, abscesses, pancreatitis, polyps, certain hemorrhoids, splenomegaly, hernias, recent abdominal surgery, GI bypass or stomach stapling, and artificial GI openings.

Did you know?

Alzheimer's disease affects only about 10% of people older than 65 years of age. Most forms of decreased mental function and dementia are caused by disuse (letting the mind get lazy).

Did you know?

About 3% of all pregnant women will give birth to twins, which is an increase in rate of nearly 60% since the early 1980s.

Did you know?

The human body's pharmacokinetics are quite varied. Our hair holds onto drugs longer than our urine, blood, or saliva. For example, alcohol can be detected in the hair for up to 90 days after it was consumed. The same is true for marijuana, cocaine, ecstasy, heroin, methamphetamine, and nicotine.
