In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
