5. Dinitrogen tetroxide is 18.46 per cent dissociated at 298 K and 1.00 bar in the equilibrium N2O4(g) 2NO2(g). Assuming that the gases are perfect. (a) calculate Kp and ArG* at 298 K. (4 points) d ln Kp (b) Evaluate (the other form of the van't Hoff equation). (2 points) d (1/T) Given: The temperature dependent of Kp is expressed in the van't Hoff d In K₂_AH* equation dT RT² Assuming that A-H is constant over a temperature range, solve the result in (b) to obtain the expression for the temperature dependence of Kp. (4 points) Given that AH = +57.2 kJ mol-¹ over the temperature range, calculate Kp at 373 K. (2 points) (d) (total 12 points)
