Q. The relationship between Gibbs free energy change (ΔG) and equilibrium constant (K) is:

गिब्स मुक्त ऊर्जा परिवर्तन (ΔG) और संतुलन स्थिरांक (K) के बीच संबंध है:

ΔG = RT ln K

ΔG = -RT ln K

ΔG = R/T ln K

ΔG = -R/T ln K

The thermodynamic relation is:

\Delta G = -RT \ln K

Where:

$R$ = gas constant (8.314 J/mol·K)
$T$ = temperature in Kelvin
$K$ = equilibrium constant
This helps predict spontaneity and equilibrium position.
