Consider the following reaction at 235°C and 1.00 atm: CH3 CI(g) + H2 (9) → CH4 (g) + HC1(g) For this reaction, the enthalpy change at 235°C is -83.2 kJ/mol. You may need to use the following data: Substance and State AĦƐ (kJ/mol) C,(J°Cmol¯1) CH3 Cl(g) 48.5 H2 (g) 28.9 CH4 (g) -75 41.3 HCl(g) -92 29.1 a Assuming that the C, values are independent of temperature, calculate AH° for this reaction at 25°C.
