1) Why are some elements in the d block poor heterogeneous catalysts? Give specific examples.
2) State 3 characteristic features of a catalyst.
3) Write an overall equation for the reaction of cyclohexene with hydrogen. And by stating a reagant and observation, give a chemical test which would show that this hydrogenation has gone to completion.
4) What feature of rhodium allows this catalyst to function?
ANY help at all please. I'm really confused.
