Some questions about heterogenic catalysis

  1. May 11, 2017 #1
    1. The problem statement, all variables and given/known data

    1. Do the molecules "seek" specific spots on the surface?

    2. The main challange in making ammonia is getting over the reaction barrier for N and H.

    3. As the temperature rises the mobility of the molecules on the surface increases.

    4. The catalytic converter in cars lowers the barrier for the reaction CO -> C + O

    Thanks!

    2. Relevant equations

    none

    3. The attempt at a solution

    I'm not sure about my answers. Keep in mind the answers are super-general and are true\false statements, and there's no need to go into much depth. I couldn't find any source for most of these so this is why I'm asking for guidance here. Thanks!

    1. From what I understood - yes. They go to spots where they are not bonded to strong to the surface but also not too weak to it.

    2. I think this statement is false. the main barrier is breaking the N2 bond and not getting N and H to react.

    3. I think this is correct, doesn't need much explanation.

    4. This one I'm unsure - is it correct or does the converter lowers the barrier for breaking the O2 ?

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
