Which scenario causes temperature variations to minimally influence reaction rate?

💡 Explanation

If zero activation energy is present, the reaction rate is almost independent of temperature, because the Arrhenius equation shows the rate constant does not change with temperature strongly; therefore A is correct; rather than rate increasing/decreasing.
