Answer: so the Effect of Catalysts on the Activation Energy Barrier. Catalysts provide a new reaction pathway in which a lower A.E. is offered. A catalyst increases the rate of a reaction by lowering the activation energy so that more reactant molecules collide with enough energy to surmount the smaller energy barrier.hope this helps
The correct answer is letter <span>d. Plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar. </span>In a typical grassland foodweb, carbon is used by plants (carbon dioxide) to create food for themselves.
