Acell consists of a gold wire and a saturated calomel electrode (s. c.e.) in a 0.130 m auno 3 solution at 25 °c. the gold wire is connected to the positive end of a potentiometer, and the s. c.e. is connected to the negative end of the potentiometer. what is the half‑reaction that occurs at the au electrode? include physical states.

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

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
