Which outcome results when an uncatalyzed chemical reaction's activation energy barrier is significantly increased?

💡 Explanation

A higher activation energy increases the energy threshold for the reaction; this is because overcoming that higher barrier requires more energy, and therefore the rate constant will decrease rather than remain same, rather than speeding up the reaction.
