= 12.5 kJ and activation energy E a = 185 kJ/mol, What is the activation energy for the reverse reaction? _____ kJ Show the work with energy diagram. 11. The rate constant for a first-order reaction is 4.60 x 10–4 –s 1 at 250°C. If the activation energy is 100.0 kJ/mol, calculate the rate constant at 300°C. ANSWER: _____ 12.
Label the x- and y-axes, the reactants, and the products on the diagram. Label the total change in enthalpy (Δ H) and activation energy (E a) on your diagram. Make sure correct units are included.
