P2B.3 The following data show how the standard molar constant-pressure heat capacity of sulfur dioxide varies with temperature: By how much does the standard molar enthalpy of SO,(g) increase when

the temperature is raised from 298.15 K to 1500 K? Hint: Fit the data to an expression of the form of Co (T) = a + bT + c/T°, note the values of the coefficients,then use the approach in Example 2B.2 to calculate the change in standard molar enthalpy.
