- Why are many reactions that occur in living systems irreversible for all intents and purposes?arrow_forwardDefine reversible reaction, dynamic equilibrium, equilibrium constant.arrow_forwardImagine 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.arrow_forward
- Which curve represents the spontaneous reaction, and which the nonspontaneous?arrow_forwardWhich 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.arrow_forwardLabel 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.arrow_forward
