27. Solution to Chemistry Problem

6. The dependence of the molar heat capacity of gaseous diatomic sulfur on temperature can be expressed by the equation
Ср= 36.108 1.506 10-3 T – 3.515 105 T–2 J/(mol K)
in the temperature range of 273 2000 K. Obtain an expression for the dependence of enthalpy on temperature for 1 mole of this gas in this temperature range (assume T1= 273 K). Calculate the change in enthalpy when heating 1 mole of gaseous sulfur from 273 to 1000 K.
