Answer to Question #261134 in General Chemistry for jena

Question

Direction:Solve for the standard Gibbs Free Energy of the following problems and show complete solution.

The old camera flash bulb used Mg metal sealed in a bulb with oxygen. At 25ºC, the reaction is:

Mg(s)+ ½ O2(g) →MgO(s)

ΔS (J/K.mol): Mg=32.7; O2=205.0; MgO=26.9ΔH (kJ/mol): Mg=0; O2=0; MgO=-601.2

Answer 1

a) $G=-197.78kJ/mol$

b) $\Delta G=-127kJ/mol$

c) $\Delta G=-568.93kJ/mol$
