Two different pathways are used to heat 2 moles of a gas from 298 K to 498 K: Path A maintains constant pressure of 2 atm, while Path B first heats at constant volume to 398 K, then at constant pressure to 498 K. Given Cp,m=20.8+0.042TC_{p,m} = 20.8 + 0.042T J mol−1^{-1} K−1^{-1} and CV,m=Cp,m−RC_{V,m} = C_{p,m} - R, what is the difference in total enthalpy change between the two paths?
