想請問各位大大 下面這題彈卡計的計算
If 1 lg mole of Cu and 1 lg mole of H2SO4 (l00 %) react together
completely in a bomb calorimeter. How many Btu are absorbed (or evolved)?
Assume that the products are H2(g) and solid CuSO4. The initial and final
temperature in the bomb are 25°C (△Hf CuSO4(S) = -769.86kJ/g-mol ,
△Hf H2SO4(l) = -811.32kJ/g-mol , Gas constant R = 8.314J/g-mol-K)
這個反應理論上△H = -769.86-(-811.32) = 41.46 會吸熱 41.46 kJ
但系統的溫度是恆溫 這要怎麼解釋 題目給Gas Conatant是跟H2有關嗎
謝謝回答喔
