Question

The equilibrium constant for a reaction is 10, value of ΔG° at 300 K is (R = 8 × 10^-3 kJ)

Options

• 11.054 kJ mol^-1

• 2.763 kJ mol^-1

• 5.527 kJ mol^-1

• - 5.527 kJ mol^-1

Answer 1

- 5.527 kJ mol^-1 

Explanation:

ΔG° = - 2.303 RT log₁₀ K

= - 2.303 × 0.008 × 300 log₁₀10

= - 5.527 kJ mol^-1
