The molar heat capacity C_P,mof SO₂(g) is described by the following equation over the range 300 K < T < 1700 K:

In this equation, T is the absolute temperature in kelvin. The ratios T€/K€ ensure that C_P,m has the correct dimension. Assuming ideal gas behavior, calculate q, w, ΔU, and ΔH if 1.50 moles of SO₂(g) is heated from 22.5°C to 1140.°C at a constant pressure of 1 bar. Explain the sign of w.
