Calculate the value of G for the following reaction. N ₂ O _ 4( ~g ) 2 NO _ 2( ~g ) if H =57.44 ~kJ and S =176 ~J ~K ⁻¹ ~mol ⁻¹ .

Options

  1. A120.20 kJ
  2. B-110.24 kJ
  3. C-46.4 ~kJ
  4. D4.64 ~kJ

Correct answer

D. 4.64 ~kJ

Step-by-step solution

aligned H & =57.44 ~kJ ~S & =176 ~J ~K ~T & =300 ~K G & = H - T S G & =57.44 ~kJ - (300 ~K 10⁻³ ~kJ ~K ⁻¹ . & =57.44 ~kJ -52.8 ~kJ =4.64 ~kJ aligned
