Options

  1. A100 ~kJ ~mol ⁻¹
  2. B150 ~kJ ~mol ⁻¹
  3. C163 ~kJ ~mol ⁻¹
  4. D2303 ~kJ ~mol ⁻¹

Correct answer

C. 163 ~kJ ~mol ⁻¹

Step-by-step solution

aligned _r G^ = & 2.303 log~Kp (R=8.314 JK ⁻¹ ~mol ⁻¹ ) _r G^ = & -2.303 8.314 JK ⁻¹ ~mol ⁻¹ 298 ~K & 2.47 10⁻²⁹ = & 163000 Jmol ⁻¹=163 ~kJ mol ⁻¹ aligned
