Calculate Keq using Standard Free Energy Change
How can we calculate the equilibrium constant (Keq) given a standard free energy change of -6.3 kJ/mol at 298 K?
a) 10⁻6.3/8.314298
b) 10⁶.3/8.314298
c) e⁻6.3/8.314298
d) e⁶.3/8.314298
Final answer: a) 10^6.3/8.314298
Answer:
The equilibrium constant (Keq) can be calculated using the Boltzmann equation: Keq = e^(∆G°/RT). Let's calculate Keq using the given values and the equation Keq = e^((-6.3 × 1000)/(8.314 × 298)). The answer is (a) 10^6.3/8.314298.
The equilibrium constant (Keq) can be calculated using the Boltzmann equation:
Keq = e^(∆G°/RT)
Where:
- ∆G° is the standard free energy change (given as -6.3 kJ/mol in this case)
- R is the gas constant (8.314 J/mol K)
- T is the temperature in Kelvin (298 K)
Let's calculate Keq using the given values:
Keq = e^((-6.3 × 1000)/(8.314 × 298)) ≈ 10^6.3/8.314298
Therefore, the answer is (a) 10^6.3/8.314298.
