Q

ΔG° =?

ΔG°’ =?

A
ΔG° = energía libre estándar en concentraciones de un mol
ΔG°' = energía libre estándar en pH 7, se puede calcular a partir de la Keq

Q

Ecuación para la ΔG

A

ΔG = ΔG° + RT ln Keq

R = constante de los gases (1.987 cal/mol)
T = temperatura en °K
Keq = productos/reactantes; C*D/A*B
