計算火商 和 電動勢 的差值 ???
(a) When 2.00 mol of SO2(g) reacts completely with 1.00 mol of O2(g) to form 2.00 mol of SO3 (g) at 25度C and a constant pressure of 1.00 atm
198kJ of energy is released as hear.Calculate deltaH and deltaE for this process.(R=8.341JK-1mol-1)
∆H = -198 / 2 = -99 kJ/mol ∆H = ∆E ∆(pV) = ∆E p∆V (定壓)p∆V = ∆nRT/n = (2 - 3) x 8.314 x 298.15 / 2 = -1239.4 J/mol = -1.24 kJ/mol ==
