The ΔG can be calculated using the formula:
ΔG = -RT ln(K)
where R is the gas constant, T is the temperature in Kelvin, ln is the natural logarithm, and K is the equilibrium constant.
Given:
K = 2.0 * 10^-31
T = 298 K
R = 8.314 J/mol K
Substituting the values in the formula,
ΔG = - (8.314 J/mol K) * (298 K) * ln (2.0 * 10^-31)
ΔG = 92.5 kJ/mol
Therefore, the ΔG for the precipitation of Al(OH)3 at 298K is 92.5 kJ/mol.
The K of Al is 2.0*10^-31 at 298k. What is ΔG at (298k) for the precipitation of according to the equation Al^3+3OH^-=Al(OH)3
