类似公式我在一些文献里看到过,但是不太会换算,您能够根据您所给的公式帮我算一下1025-1288K之间分解压的范围吗?感激
,
logP就是对蒸气压取P以10为底的对数。
举个例子:
对于1025K,蒸气压的对数按上述公式(单位是KPa):
log P= 9.15 −12798 /T = 9.15 −12798 /1025≈−3.335854
则蒸气压:P=10的负3.335854次方=0.00046147(kPa)≈0.46Pa
对于1288K:
log P= 9.15 −12798 /1288 = 9.15 −12798 /1288≈−0.78633540
则蒸气压:P=10的负0.78633540次方≈0.16356(kPa)≈163.56Pa
楼主自己验算一下吧。上述计算未考虑公式中的±波动值。
