- Sketch a qualitative reaction energy diagram for a chemical reaction with and without a catalyst. Assume the uncatalyzed reaction is endothermic. Note: Because the sketches are only qualitative, the energies in them don't have to be exact. They only have to have the right relationship to each other. For example, if one energy is less than another, that fact should be clear in your sketch.arrow_forwardDefine " reaction mechanism." Define "nucleophile." What electronic features characterize a nucleophile? Define "electrophile." What electronic features characterize an electrophile?arrow_forwardFor each reaction in question 20, sketch a reaction coordinate energy diagram indicating the starting materials, transition states and any intermediates, if present, in the reaction. Don't worry about the absolute energy of starting materials and products but you can assume that the product is more stable than the starting materials.arrow_forward
- Using the concept of collisions and molecular motion, explain why mixing a reaction mixture can speed up the rate of reaction.arrow_forwardConsider the reaction coordinate diagram for the reaction below. How many steps is this reaction? How many intermediates are in the reaction? How many transition states are in the reaction? What is the rate limiting step?arrow_forwardIs this reaction multi-step or single-step? What is the relationship between reactant and product? How would the rate of reaction change if the solvent was methanol?arrow_forward

- What is the effect on the rate constant and reaction rate when reaction temperature is increased? The rate constant will be greater, and the reaction rate will be higher. The rate constant will be smaller, but the reaction rate will be higher. The rate constant will be smaller, and the reaction rate will be lower.arrow_forwardwhat is the rate of reaction for this equation?arrow_forwardRefer to the reaction energy diagram to answer parts (a) through (e).
