Question

When you added different concentrations of KMnO4 to wells in a petri plate, they had different larger or smaller rings of diffusion. Why were some larger or smaller

Answer 1

Faster or slower diffusion depending upon the concentration

Step-by-step explanation:

Given: When you added different concentrations of
`KMnO_4` to wells in a Petri plate, they had different larger or smaller rings of diffusion

Solution:

If we add more concentration of
`KMnO_4`, there will be more gradient which results in faster diffusion.

If we add less concentration of
`KMnO_4`, there will be less gradient which results in slower diffusion.
