Two moles of H_2 in a close system are heated from 25 degree C to 55 degree C at a constant pressure of 2 atm. Assume ideal gas and use C_p as provided below. C_P degree (J K^-1 mol^-1) = a + bT + c/T^2 with parameter a = 27.28 J K^-1 mol^-1, b = 3.26 times 10^-3 J K^-2 mol^-1, and c = 0.5 times 10^5 J K mol^-1 Starting with the 1^st law of thermodynamics, show that for a close system dH = Q for a constant pressure process. Calculate Delta S_sys, Delta S_surr, Delta S_total, Delta H, Delta U, Q, and W.
