which statement is usually true about the relationship between activation energy and reaction rates?\nlow…

Brief Explanations:

Activation energy is the minimum energy required for a reaction to occur. A higher activation - energy barrier makes it more difficult for reactant molecules to transform into products, thus slowing down the reaction rate. Lower activation - energy barriers allow reactant molecules to more easily reach the transition state and form products, resulting in higher reaction rates.

Answer:

High activation energy barriers result in low rates.
