Consider the following reaction: CS2(l) + 3O2(g) arrow CO2(g) + 2SO2(g); Delta H = -1075.2 kJ/mol a. What is the change in the enthalpy if 10.0 grams of SO2 are produced? b. What mass of CO2 is formed if 500.0 kJ of energy is released?
Thermodynamic modeling of CO2 solubility into an aqueous solution of N-methyldiethanolamine using EoS/G(E) approach and different Alpha-functions This study has been dedicated to modeling the aqueous CO2+ N-methyldiethanolamine (MDEA) system's vapor-liquid equilibrium within the temperature range 297.7...
the enthalpy change of combustion of H2 is needed, which is -286 kJ/mol.(i) 3C (s) + 3O2 (g) = 3CO2 (g) ∆H₁ = (-393.7)*2 = -1181.1 kJ (ii) 3H2 (g) + (3/2)O2 (g) = 3H2O (l) ∆H₂ = (-286)*3 = -858 kJ ...
1 S(s) 1 2 O2(g) SO3(g) H1 H 2 H 3 94.58 kcal 由上面這個例子我們可以看出,黑斯定律允許熱化學反應式相加減,所以黑斯定律也稱作熱 化學加成律 addition law of thermochemistry。其實不只反應熱遵循黑斯定律,所有伴隨化學反 應所發生的能量變化都遵守黑斯定律,自由能以及亂度也都可以相加減。
The sign of the enthalpy of the reaction reverses. 我們有專家為這個問題所編寫的解答! Consider the intermediate chemical reactions. The final overall chemical equation is CaO(s)+CO2(g)---> CaCO3(s). When the enthalpy of this overall chemical equation is calculated, the enthalpy of the second...
