Answer:
The change in the Gibbs function of reaction on going from crust to core, dG=291442.4 J/mol
Explanation:
dG=vdp-sdT
Where T is the temperature .
P is the pressure.
S is entropy
V= 1cm3 =10-6 m3
P= 3*10∧6 atm = 3*10∧11 pa
The temperature at the center of the earth, Tc = 4*103 °C. : The temperature at the sufrace (crust) of the earth, Ts =298K.
Subistuting the values
dG = (10-6 *(3*1011-105) - (2.1(4373-298))
dG=291442.4 J/mol.
