Is nickel metal a suitable catalyst for the catalytic converter? Explain why or why not.
What are the rate expressions for the two cases?
At high temperature limit when the fraction of catalyst surface area covered by reactants is zero, what will the apparent activation energy Eapp be?
Use the techniques suggested in Exercise 2.2 (Assignment 2) to answer the above problem.
In what region of the radiation spectrum are these photons?
Explain how the energy of the photons activates solid TiO2 for possible catalytic activities when light of this region is absorbed by titanium dioxide?
How does the excitation lead to the photocatalytic decomposition of water? What techniques are used to overcome the difficulties. (See Section 6.5 of Inorganic Chemistry by Swaddle.)
Give an example to illustrate how the activation energy is affected by the use of a heterogeneous catalyst.
