Question

a scientist carries out a reaction twice. in trial a, the scientist combines the reactants in a container. in trial b, the scientist combines the reactants in the same container, but she also adds a catalyst. if everything else is the same about the two trials, what is most likely true about trial b? it will produce more product than trial a. it will produce different products than trial a. it will have a lower activation energy than trial a. it will have a higher overall energy output than trial a.

Explanation:

A catalyst lowers the activation energy of a chemical reaction without changing the amount of product formed or the products themselves, and also does not change the overall energy output of the reaction.

Answer:

It will have a lower activation energy than Trial A.
