  4.  Write the Arrhenius Equation

    5.  

     

  5. The activation energy for the decomposition of HI(g) to H2g) and I2(g) is 186 kJ/mol. The rate constant at 555K is 3.52 x 10-7­L/mol s. What is the rate constant t 645K?

    6.  

     

  6. The reaction

    (CH3)3CBr + OH-    → (CH3)3COH + Br-

    in a certain solvent is first order with respect to (CH3)3CBr and zero order with respect to OH-.  A plot of ln(k) versus 1/T was constructed that resulted in a straight line with the slope of -1.10 x 104 K and a y intercept of 33.5.

      7.  

    • Determine the Ea.

      •  

    • Determine A.

      •  

    • Calculate k at 298K.

     

     

  7. Consider

    NO2(g) + CO(g)    → NO(g) + CO2(g)

    If the activation energy is 125 kJ/mol, and ΔE for the reaction is -216 kJ/mol. What is the activation energy for the reverse reaction?
