CAS号:

性质:也称标准生成焓(standard enthalpy of formation)。由标准状态(压力为100kPa,温度TK)下最稳定单质生成标准状态下单位物质的量的化合物的热效应或焓变(△H)称为该化合物的标准生成热(或焓),以符号△fH表示。最稳定的单质的标准生成热规定为零。各种物理化学手册中给出的生成热是在温度为298.15K时生成lmol化合物的标准生成热,叫做标准摩尔生成热(或焓),用符号表示。例如,下列反应在298.15K及101325Pa条件下的摩尔反应热是-393.51kJ/mol。C(固,石墨)+O2(气)=CO2(气)根据定义,CO2的标准摩尔生成热=-393.51kJ/mol
