12.) Draw an energy diagram indicating AG, AG² , the transition state, products and reactants. What determines the rate of a reaction? What determines the ratio of products to reactants at equilibrium? How does an enzyme affect the reaction? What determines the rate of a reaction How an enzyme might affect the reaction An enzyme will not affect the following aspect of a reaction

In the diagram below, which pathway would represent the catalyzed reaction? reaction Progress Blue line (dotted line) O Red line (solid line) Energy

⦁    4.  Make your own energy diagram for an exothermic reaction that does not include a catalyst and one with a catalyst (Be sure each line is a different color or labeled). Label the axis of the diagram. Then, state what a catalyst is and how a catalyst affects the reaction rate.

2. Which of the following is most similar to a system at equilibrium? * O a shift change at an assembly plant involving two crews of 100 employees O a popcorn maker when the popcorn starts to pop the water in a pool when swimmers start to splash water out of the pool a burning candle salt concentrations in the oceans

Please don't provide handwriting solution

Which of the following are true statements about catalysts (choose all that apply)? O A catalyst effectively creates an extra path for the reaction to travel that is higher in energy O A catalyst is completely consumed in a reaction O A catalyst works by lowering the energy barrier to a reaction O A catalyst helps keep reactants stable at higher temperatures O An enzyme is a biological catalyst O A catalyst is a substance that increases the rate of a chemical reaction

Graph of concentration versus time Concentration Time The graph above represents the change in concentration of a reactant versus time during a reversible reaction. The diagram below that shows the effect of a catalyst on the change in concentration for this reactant relative to its initial change is Concentration ☐ Concentration ☐ Time Concentration ► Time Concentration Time Time

Which of these changes would increase the rate of a reaction?     Decrease concentration     Use solid rather than a gaseous form     Add catalyst     Decrease temperature

On an energy graph, the length of vertical lines represents _____. whether energy is released or absorbed the number of atoms in the activated complex the number of reactant and product atoms the amount of released or absorbed energy

Energy (kJ) Energy (kJ) Why do catalysts increase reaction rate? Catalyst Effect on Reaction Path Examples. Catalytic Convertors Reactants Products Interpret the following potential energy diagrams (reaction coordinate diagrams) Reaction 1 Reaction 2 450T B. A+B Time Reaction coordinate, A B A + B → C 1. Which reaction is endothermic? 2. What is the activation energy of Reaction 1? 3. What is the AHrxn of reaction 1? 4. What is the activation energy of reaction 2? 5. What is the AHnn of reaction 2? 6. Sketch the effect of a catalyst on both reactions 7. Does a catalyst effect the AHrn?
