Question
We start with a sample of pure A(g). The following equilibrium is established 2 A(g) B(g) + C(g) The total pressure is 8.77 atm and the temperature is 25.0oC. The partial pressure of A(g) is 5.09 atm. Calculate the value of the standard free enthalpy change (in kJ) of this reaction at 25.0oC.
Question 3 :
On commence avec un échantillon de A(g) pur. L'équilibre suivant s'établit
2 A(g) <---> B(g) + C(g)
La pression totale est 8.77 atm et la température est 25.0°C. La pression partielle de A(g) est 5.09 atm. Calculez la valeur de la variation d'enthalpie libre standard (en kJ) de cette réaction à 25.0°C.
