Dinitrogen tetroxide is a common rocket fuel which at 25℃ dissociates into nitrogen dioxide forming an equilibrium between an equilibrium between the two gases.The equilibrium mixture depends on the temperature of the mixture.What is the change in gibbs energy if the quantities of the gases present in a 1L container are 11.5g N2O4 and 2.54g NO2.The standard gibbs free energy for the reaction is +4853J
