What is best reason for why microwave irradiation heats a chemical reaction? Microwaves cause the individual bonds to vibrate more rapidly which is then transferred into kinetic energy. Microwaves change the spin state of the nucleus which is then transferred into kinetic energy. Microwaves directly accelerate a compounds translational motion, increasing their kinetic energy. O Microwaves interact with the dipoles in the chemical system which results in an increase in kinetic energy

Corrected True/False: Indicate whether each statement is true or false. If false, correct the statement to make it true. 10. A formation reaction has elements in their standard states as reactants. 11. In exothermic reactions the products have more kinetic energy than the reactants. 12. The process of nuclear decay is a first order reaction. 13. The rate-determining step is the fastest step in a reaction mechanism.
None
Enzymes catalysts that increase the rates of biochemical reactions. are True False
Kinetics describes reaction rates. How fast are reactants converted toproducts?
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.
The red arrow (which we use in organic chemistry to indicate the movement of one or two electrons during a reaction) must never, ever, ever start at a O positive or partial positive charge O negative or partial negative charge radical O double bond
Reaction intermediates differ from activated complexes in that___. A. they are stable molecules with normal bonds and are frequently isolated. B. they are molecules with normal bonds rather than partial bonds and can occasionally be isolated. C. they are intermediate structures which have characteristics of both reactants and products. D. they are unstable and can never be isolated. E. all reactions involve reaction intermediates, but not all have activated complexes.
How is a simple reaction different from a complex reaction?
What do you call the high-energy complex that forms from the collision of reactants, and which subsequently falls apart to yield the products? a. steady state b. catalyst c. intermediate d. transition state
Explain the differences between molecular conjugation and bioconjugation for advanced drugdelivery. Please provide an example of each
The following are some of the steps in the Born-Haber cycle for Mg (s) + Br2 (l) → MgBr2(s). Check all of the reactions that you would expect to be exothermic. Mg (s) → Mg (g) Mg2+(g) + 2 Br- (g) → MgBr2 (s) Br (g) + e → Br- (g) Mg (g) → Mg+(g) + e Mg+ (g) → Mg2+(g) + e
Write why is True if the statement conforms to the concept of rate law and also write why is False if it does not. 1. Rate law states that overall order of reaction can be determined by adding the reactionorders of the reactants.reactant concentration.3. All reactions proceed at the same rate.4. The balanced equation can be used to determine the rate of reaction.5. The slowly reactive or unreactive speciesin a reaction can be identified using rate law.
