我们的反应需要计算反应热,在rstoic反应器中,有个heat of reaction ,怎么设定呀? 截图在下面:...
燃烧热的计算公式为:ΔH=Q放-Q吸,其中ΔH为燃烧热,Q放为可燃物完全燃烧放出的热量,Q吸为可燃物吸收的热量。例如,在25°C和101kPa下,1mol气态H2与0.5mol气态O2反应生成1mol液态H2O时,放出285.8kJ的热量,即H2(g)+ O2(g)= H2O(l)ΔH=-285.8kJ/mol。 燃烧热的大小与可燃物的种类、反应条件等因素有关...

How much heat is required to convert 45.0 g of ethanol at−144∘Cto the vapor phase at78∘C? Heat: The heat that gets either evolved or absorbed in any particular chemical reaction that occurs at a temperature that is constant is referred to as the ...
Neutralization Reaction Thermochemistry: Chemistry reactions inevitably involve absorption or emission (taking in or giving off) of thermal energy/heat. If the process gives off heat, it is called exothermic. If it takes in heat, it is called endothermic. The state of the resulting molecules or ...
