Page 1 of 2 Pre-lab Questions for Experiment #4 Chemical Reactions 1) A chemical equation uses chemical symbols to show what happens during a chemical reaction: reactants → products. A chemical equation is a shorthand notation of a chemical reaction. Once the reactants and products are known, then we can balance the chemical equation by the Law of Conservation of...

Problem (15 points) A complex reaction (A-> products) involving 2 enzymes occurs in an ideal steady state mixed flow reactor (constant flowrate, outlet concentration is the same as reactor concentration). Both reactions consume reactant A. See the diagram below. The reaction constants for the enzymes and reactor volume/flow are given below. If needed, enzymatic reaction rate model is, r= -Vm*C/(Km+C)...
