Heterogeneous catalysis Rate of catalytic reactions
Why does heterogeneous reactions have 0 rate? Even if there is more than 1 molecule taking part in the process
Unfortunately I don't have any specific one. I heard about it during lecture, our professor said that 0 rate is popular among heterogeneous catalysis. Also there was something about the amount of active sites
@chaoticgood Could you clarify this information in more detail? It just seems to me that you didn't quite understand, and it turns out that the question is not entirely clear.
Most likely, it was meant here that the overall speed of a heterogeneous reaction is determined by the slow stage of the process.
@damiryagudin Is the principle of "rate of reaction is determined by the slow stage of the process" works only for heterogeneous catalysis, or is it more universal?
In general, this is universal, for example, for multi-stage reactions where intermediate compounds are formed
@chaoticgood Only for heterogeneous systems that have a multi-stage mechanism. Note: Heterogeneous catalysis may not be a prerequisite.
