Equilibrium Constant (K) vs Standard ΔG°
सूत्र
## Equilibrium Constant from ΔG° ### Formula **K = e^(−ΔG° / RT)** Equivalently: **ΔG° = −RT ln(K)** Where: - **K** = equilibrium constant - **ΔG°** = standard Gibbs free energy change (J/mol) - **R** = 8.314 J/(mol·K) - **T** = temperature (K) Large K (K >> 1) means products are favored. Small K (K << 1) means reactants are favored.
हल किया गया उदाहरण
A reaction with ΔG° = -10 kJ/mol at 298 K.
- 01K = e^(-ΔG°/RT)
- 02K = e^(-(-10000)/(8.314 × 298))
- 03K = e^(10000/2477.6)
- 04K = e^(4.036)
- 05K = 56.6
अक्सर पूछे जाने वाले प्रश्न
What does the equilibrium constant tell you?
K indicates the ratio of product to reactant concentrations at equilibrium. K > 1 favors products; K < 1 favors reactants.
Does K change with temperature?
Yes. K depends on temperature through ΔG° = -RT ln(K). For exothermic reactions, K decreases with increasing temperature.
What is the difference between K and Q?
K is the equilibrium constant (at equilibrium). Q is the reaction quotient (at any point). If Q < K, reaction proceeds forward; if Q > K, it proceeds backward.
