Question

Using the following data,

ΔG°_f NaHSO₄(s) = −992.8 kJ/mol

ΔG°_f NaOH(s) = −379.7 kJ/mol

ΔG°_f SO₃(g) = −371.1 kJ/mol

What is the K_c expression for the reaction? What are the K_c value and ΔG° value for the reaction at 298 K?

NaHSO₄(s) ⇌ NaOH(s) + SO₃(g)

Accepted Answer

The K_c expression for the reaction is K_c = [SO₃(g)]
Its K_c value is 4×10⁻⁴³ and ΔG° value is 242.0 kJ

Answer

The K_c expression for the reaction is K_c = [SO₃(g)]
Its K_c value is 3×10⁴² and ΔG° value is 242.0 kJ

Answer

The K_c expression for the reaction is K_c = [SO₃(g)]
Its K_c value is 2×10⁴² and the ΔG° value is −242.0 kJ

Answer

The K_c expression for the reaction is [SO₃(g)]
Its K_c value is 4×10⁻⁴³ and ΔG° value is −242.0 kJ
