9. [ Calculate AH for the process in which Cl2(g) initially at 298.15 K at 1 bar is heated to 690. K at 1 bar. Use the temperature-dependent heat capacity for Cl₂(g) below. How large is the relative error if the molar heat capacity is assumed to be constant at its value of 298.15 K over the temperature interval? CP,m= 33.95 J K-¹ mol-¹ for Cl2(g) at 298.15 K. Cp.m JK-1mol-1 = 22.85 +0.06543 – 1.2517 x 10-4+1.1484 x 10-7 K
