Final answer:
To find the value of Kc for the reaction at 298 K, you can use the equation Kc = e^(ΔG°/RT), where ΔG° is the standard free energy change, R is the gas constant, and T is the temperature in Kelvin.
Step-by-step explanation:
The value of Kc for the reaction at 298 K can be calculated using the standard free energy change:
Kc = e^(ΔG°/RT)
where ΔG° is the standard free energy change, R is the gas constant (8.314 J/mol K), and T is the temperature in Kelvin (298 K).
By substituting the given values, we can calculate Kc.
