Two moles of H₂ in a close system are heated from 25 °C to 55 °C at a constant pressure of 2 atm. Assume ideal gas and use C, as provided below. C₂° (J K ¹ mol ¹) = a+bT+c/T² with parameter a=27.28 J K¹mol¹, b=3.26x10³ J K²²mol¹, and c=0.5x10³ J K mol-¹ (a) Starting with the 1st law of thermodynamics, show that for a close system dH = Q for a constant pressure process. (b) Calculate AS sys, ASsurr, A Stotal, AH, AU, Q, and W. Two moles of H₂ in a close system are heated from 25 °C to 55 °C at a constant pressure of 2 atm.
