Differential Rate Law

[Caroline C 1G]

Is it possible for none of the reactant concentrations to affect the initial rate? If so, what would the rate equation look like?

[Esin Gumustekin 2J]

Yes it is possible for none of the reactant concentrations to affect the rate. This would mean that the order is 0. I believe Dr. Lavelle is going to go through examples of this next week.

[Lily Sperling 1E]

Yes this is possible and it means that the order would be 0! I am not sure if Dr. Lavelle will cover this but it is in the book so I assume so.

Yes, as stated before, this kind of reaction would be a zero order reaction, which means that the rate of reaction would depend only on the rate constant, k. I think the rate equation in this scenario would then just be Rate=K, since the exponents on your reactant concentrations would be 0, which would mean that the K is just being multiplied by 1.
