1) You are attempting to separate value from serine on a C18 column with a methanol:acetic acid mobile phase. You get the following profile:a) Label the two peaks (valine and serine) (2 points)b) Is this reverse phase or normal phase chromatography

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
