Negative k?

Postby Hellen Truong 2J » Fri Mar 09, 2018 8:51 am

Is it possible for k to be negative for any order reaction?

I don't think so. Rate is always a positive value, and since rate=k[A], then k cannot be negative.

Since there can't be a negative amount of products or reactants that exists in a chemical equilibrium, the rate constant must be positive.

k itself cannot be negative but the slope involving k as with 1rst order or 0 order reactions can be negative.

k cannot be negative, but there can be reactants with a negative sign in their reaction order
