Weba) A given enzyme catalyses just one type of reaction. b) While most enzymes are proteins, some are composed of RNA. c) The activity of enzymes is typically impaired at high temperatures. d) Enzymes act to lower the activation energy of a reaction by stabilising the transition state, but do not participate chemically in the reaction. WebQuestion 4 0.21 pts Consider the 2nd Law of Thermodynamics. For a spontaneous process, if the entropy change of the system is negative, what can we conclude about the entropy change of the surroundings? increases for a spontaneous process. C The entropy change of the surroundings must also be negative because the entropy of the universe ...
WebAnswer (1 of 5): The process is considered as sponataneous if ∆Suniverse>0. Because only then heat exchange can take place sponataneously. If ∆S=0 then the process is at equilibrium, it's because at the equilibrium entropy of the process is maximum and change in entropy is zero. This is because a... WebTo balance a nuclear reaction. Unstable nuclei spontaneously emit radiation in the form of particles and energy. This generally changes the number of protons and/or neutrons in the nucleus, resulting in a more stable nuclide.
WebApr 8, 2024 · A spontaneous chemical reaction is an irreversible process where you can’t get the ingredients back without the external agents. [Image will be uploaded soon] Equation of Spontaneous Reaction. We can predict the spontaneity Chemistry of a reaction with the change in its total entropy. This is defined as the spontaneity of any process.
