The reaction rates of most reactions increase rapidly with increasing solvent viscosity.

Question

Quizplus · Accepted Answer

The reaction rates of most reactions actually decrease or remain unaffected by increasing solvent viscosity. This is because a higher viscosity hinders molecular diffusion and makes it more difficult for reactant molecules to come into contact with each other. However, there are some exceptions where certain reactions may actually exhibit a slight increase in rate with increasing viscosity, but this is not the general case.
