From plotting the natural logarithm of the equilibrium constan (lnKeq) as a function of the inverse of temperature 1/T (K-1) for the reaction 2SO2(g)+O2(g)2SO3(g). The slope = 20000 K was obtained. The 1) Calculate the enthalpy change of the reaction Ho in kJ/mol R= 8.314 J/ mol.K 2) Calculate the entropy change of the reaction So in J/mol.K at 298 K
