At 300 ~K the enthalpy change for the following reaction is -2800 ~kJ ~mol ⁻¹

Options

  1. A-2802.49
  2. B-2800.00
  3. C-2814.94
  4. D+2802.49

Correct answer

B. -2800.00

Step-by-step solution

aligned & H = U + P V = U + n _ g RT & U = H - n _ g RT =(-2800)-(0 0.082 300) & =-2800 ~kJ ~mol ⁻¹ & aligned
