Answer : The value of of vaporization for arsine and its normal boiling point is, 17694.3 J/mol and 209.9 K respectively.
Explanation :
First we have to calculate the value of of vaporization for arsine.
The Clausius- Clapeyron equation is :
where,
= vapor pressure of arsine at = 35 torr
= vapor pressure of arsine at = 253 torr
= temperature of arsine =
= temperature of arsine =
= heat of vaporization = ?
R = universal constant = 8.314 J/mol.K
Now put all the given values in the above formula, we get:
Now we have to calculate the normal boiling point of arsine.
The Clausius- Clapeyron equation is :
where,
= vapor pressure of arsine at = 35 torr
= vapor pressure of arsine at normal boiling point = 760 torr
= temperature of arsine =
= normal boiling point of arsine = ?
= heat of vaporization = 17694.3 J/mol
R = universal constant = 8.314 J/mol.K
Now put all the given values in the above formula, we get:
Hence, the value of of vaporization for arsine and its normal boiling point is, 17694.3 J/mol and 209.9 K respectively.
