Explain in your own terms the difference between a spontaneous reaction and one that occurs instantaneously, and what causes this difference.
Step by step
Solved in 2 steps
- Explain in your own words the difference between a spontaneous reaction and one that occurs instantaneously, and what causes this difference.List the four factors that influence the rate of a chemical reaction and state whether increasing the factor will increase or decrease the rate of the reaction.Imagine you are working in a lab, and you are performing two chemical reactions. You notice that Reaction A occurs much faster than Reaction B, and that both reactions release the same amount of heat. Which of the following conclusions can be made from your observation? Reaction A has the same activation energy as Reaction B, and the AG of Reaction A is more negative (i.e., a larger negative number) than the AG for Reaction B. Reaction A has a lower activation energy than Reaction B, and the AG of Reaction A is the same as the AG of Reaction B. Reaction A has a higher activation energy than Reaction B, and the AG of Reaction A is the same as the AG of Reaction B. Reaction A has the same activation energy as Reaction B, and the AG of Reaction A is less negative (i.e., a smaller negative number) than the AG for Reaction B.
- Define reversible reaction, dynamic equilibrium, equilibrium constant.Which of the following is correct regarding enzymes? Enzymes can speed up the rate of reaction by shifting the equilibrium of the reaction forward. Enzymes can make a nonspontaneous reaction spontaneous. Most enzymes are made up of DNA and RNA and are named based on the reaction that they catalyze. Enzymes can increase the rate of a reaction, but do not shift the equilibrium of a reaction.Which of the following describe(s) an exergonic reaction? energy is released non-spontaneous energy is absorbed spontaneous
- Label the following statements true or false: (a) A reaction is said to be spontaneous when it can proceed in either the forward or reverse direction. (b) A spontaneous process always happens very quickly.Define enzymesIn the following reaction, which is/are substrate(s), enzyme, products, allosteric inhibitor(s), negative regulator(s), and reactant(s)? Z A + B → C +D
