Summary Introduction

Concept introduction: Enzymes are the biocatalyst that accelerate the chemical reactions. These are protein molecules that speed up the reaction. Enzymes act on the substrate molecule and convert into product. These are specific in nature in which they act on its substrates.

Expert Solution & Answer

Answer to Problem 1E

Correct answer: The best description for enzyme is: It increases the rate at which a chemical reaction approaches the equilibrium relative to its uncatalyzed rate. Hence, option b. is the correct answer.

Explanation of Solution

Reason for the correct statement:

Option b. is given as, “It increases the rate at which a chemical reaction approaches equilibrium relative to its catalyzed rate”. If the activation energy is low, the rate will be faster. Enzymes speed up the reactions by lowering the activation energy. However, the reaction reaches the equilibrium much faster when the enzyme is present as the rate of the reaction is increased. Hence, option b. is the correct answer.

Reasons for the incorrect statements:

Option a. is given as, “It allows a chemical reaction to proceed extremely fast”. The factors that deal with the rate of chemical reaction that proceeds the reaction faster is called the chemical kinetics. Thus, the given statement is not a description of enzyme. Hence, option a. is incorrect.

Option c. is given as, “It makes a reaction thermodynamically favorable”. The reaction will be thermodynamically stable due to the reaction that occurs spontaneously, without the need for energy to be added. Therefore, the given statement explains that kinetics is related to reactivity. Hence, option c. is incorrect.

Conclusion

Conclusion: Enzymes increase the rate at which a chemical reaction approaches equilibrium relative to its catalyzed rate.

2. For the flow of fluid over a flat membrane of length 10cm, determine the length-average mass transfer coefficient. The relevant properties of the system are u=0.01cm²/s, D=5 x 106 cm²/s, and v = 5.0 cm/s.

Background Freezing isn't the only challenge in cryopreservation - thawing can be just as difficult. A microwave oven seems like a nice solution, since it deposits energy quickly and microwaves are non-ionizing radiation (they do not cause DNA mutation). However, water absorbs microwaves more effectively than ice does, meaning that the portion of an organ that has already melted will get warmer at a higher rate than the remaining ice – the opposite of what we want! - The transmission of radiation through a weakly absorbing material such as ice or water can be modeled by Beer's law, which assumes that the rate of absorption at a depth x is proportional to the local radiation intensity I(x) times an absorption coefficient, which is often written as μ or a or just µ). Noting that absorption decreases the intensity, we can write a differential equation a Solving the differential equation with the boundary condition on the surface being gives the relationship For a standard microwave oven…
