A carbon atom that is surrounded by four hydrogen atoms has a molecular geometry. This geometry results from the arrangement of the hybrid orbitals around the carbon atom. They are formed when the s-orbital and -orbitals mix, or hybridize.

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
