The formation constant for the reaction Is K_f = 1.7 × 10⁷ at 25°C. What is $\Delta$G°at this temperature?

Question

Quizplus · Accepted Answer

The standard Gibbs free energy change for the reaction is given by:
ΔG° = -RT ln K
where R is the gas constant, T is the temperature in Kelvin, and ln is the natural logarithm.

Substituting the given values, we get:
ΔG° = - (8.314 J/mol·K) × (298.15 K) × ln (1.7 × 10^17)
ΔG° = -41.3 kJ/mol

Therefore, the correct answer is E (-41 kJ).

The Formation Constant for the Reaction Is Kf Δ\DeltaΔ
