For a phase change, H0 = 2 kJ/mol and A S0 = 0.017 kJ/(K•mol). What are AG and the spontaneity of the phase change at 500 K?

ΔG = -6.5kJ/mol at 500K

Explanation:

We can find ΔG of a reaction using ΔH, ΔS and absolute temperature with the equation:

ΔG = ΔH - TΔS

Computing the values in the problem:

ΔG = ?

ΔH = 2kJ/mol

T = 500K

And ΔS = 0.017kJ/(K•mol)

Replacing:

ΔG = 2kJ/mol - 500K*0.017kJ/(K•mol)

ΔG = 2kJ/mol - 8.5kJ/mol

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
