Question

a. Calculate the delta H, delta G, and equilibrium constant for the reaction of methane with Cl2 to give CH3Cl and HCl. Use the following information for your calculations:
 Bond Dissociation Energies:
 CH3-H (104.8kcal/mol), Cl-Cl(59.0 kcal/mol), CH3-Cl(85.0 kcal/mol), and H-Cl (103.2 kcal/mol).
 Thermodynamic data:
 DeltaSrxn= + 0.29 x 10^.3 kcal/mol K, T=0 degrees celcius, and R= 1.987 cal/mol

find what K=

Jennifer · Answer

I got that delta H=-24.4 and delta G=-24.3... But keep getting the equilibrium constant (K) wrong... Can someone please help...
