The approximate empirical expression for variation of molar heat capacity at constant pressure Cpm with temperature is given by Cpm a + bT + T2 [4] Calculate the change in molar enthalpy AH, when the given gas is heated from 25 °C to 500 °C using the expression above. The constants a, b, and c are available in Table 2B.1. AT= 500 – 25 = 475K for Br2 : a-37.32 b=0.50×10³K! c=-1.26×10°K?
