A flask is charged with 1.50 atm of N204 (g) and 1.00 atm of NO2 (g) at 25 C and the following equilibrium is achieved: N 20 4 (g) 2 NO 2 (g) After the equilibrium is reached, the partial pressure of NO 2 is 0.612 atm. What is the value of the standard Gibbs energy, in kJ, for the reaction? OA. 4.70 OB. 3.74 Oc. 2.91 OD. 2.19
