A dimerization reaction of 2R molecules occurs on a catalyst surface to form a product P. The reaction proceeds through the following mechanism: (1) R(g)+R (2) 2RPP+ (3) PP(g)+ Transition state and reaction energies on three different catalyst surfaces are given in the table below: (a) Construct a potential energy reaction coordinate diagram for this reaction on the three different catalysts. (b) Derive an analytical expression for the rate of reaction on Ag(211) using the microkinetic model methodology. Use the potential energy diagram derived in part (a) to identify the rate limiting step on Ag(211). Calculate and plot the overall rate of reaction as a function of temperature for the Ag(211) catalyst
