Which outcome reduces energy needed for a chemical reaction?

A)Addition of a catalyst provides pathway✓

B)Increasing reactant initial concentration greatly

C)Raising system temperature to extreme levels

D)Applying strong electromagnetic field throughout reaction

💡 Explanation

A catalyst lowers activation energy by stabilizing transition states via adsorption, hence reaction rate increases because a larger fraction of molecules possess that lower activation energy; rather than options that only increase collisions.
