E. [tex]2.48 \times 10^3[/tex] kJ

Answer :

Final answer:

The value of ΔGº for the reaction is calculated using the equation ΔGº = -RT ln(K), where R is the gas constant and T is the temperature in Kelvin. Substituting the given values, we can calculate the value of ΔGº.

Explanation:

To calculate the standard Gibbs free energy change (ΔGº) for a reaction, we can use the equation ΔGº = -RT ln(K), where R is the gas constant and T is the temperature in Kelvin.

In this case, the given information is that the equilibrium constant (K) for the reaction is 6.32 x 10^6 at 298 K. The gas constant (R) is given as 8.31 x 10^3 kJ/K.

Substituting the values into the equation, we have:

ΔGº = - (8.31 x 10^3 kJ/K) x (298 K) x ln(6.32 x 10^6)

Calculating this expression gives us the value of ΔGº for the reaction.
