Question 1

For the reaction: Mg(s) + AgNO3(aq) → Ag(s) + Mg(NO3)2(aq)

Ag+(aq) + e-→ Ag(s) = 0.800 V
Mg2+(aq) + 2 e-→ Mg(s) = -2.356 V

Determine ΔG°.
◦ -300.3 kJ/mol
◦ 304.5 kJ/mol
◦ 609.0 kJ/mol
◦ -304.5 kJ/mol
◦ -609.0 kJ/mol

Question 2

Given that red = -1.66 V for Al3+(aq)/Al(s) at 25 °C, find and E for the concentration cell expressed using shorthand notation below:

Al(s) Al3+(aq, 1.0 × 10-5 mol L-1) Al3+(aq, 0.100 mol L-1) Al(s)

= 0.00 V and E = +0.24 V
= 0.00 V and E = +0.0789 V
= -1.66 V and E = -1.42 V
= -1.66 V and E = -1.54 V

Did you know?

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.
