the chemical reaction for the dissociation of dinitrogen tetroxide is N2O4(g) ---> 2N)2(g) the reported standard-state gibbs free energy change for this reaction over a limited temperature range is deltaGrxn(T) = 57.33 - 0.17677T kJ/mol of N2O4 reacted for the pure component, ideal gas at 1 bar standard state and T in kelvins. a.) what is the standard-state heat of reaction for the dissociation of dinitrogen tetroxide? b.) determine the equilibrium composition of this mixture of 50C and 0.1, 1, and 10 bar. c.) repeat the calculation at 200C
