Suppose that the activation energy for a certain reaction is 30 kJ/mol and the enthalpy of reaction is –75.0 kJ/mol. What activation energy is required to initiate the reverse reaction that converts the products into reactants?
The standard enthalpy of a reaction, AH, is the energy or enthalpy change associated with transforming reactants into products, where "standard", denoted °, implies reaction conditions of 25°C, 1 atm and/or 1 M. Standard enthalpies of a reaction can be estimated by assuming that all reactant bonds are broken before forming all product bonds: AHTD =( enthalpies of bonds broken) - (2 enthalpies of bonds formed) Using the information below, calculate AH°r (kJ) for the reaction of H2(g) + Cl2(g)...
