what is the difference between activated complex and transition state?

However, it differs from the transition state in that the transition state represents only the highest potential energy configuration of the atoms during the reaction while the activated complex refers to a range of configurations near the transition state that the atoms pass through in the transformation from products ...

As nouns the difference between transmission and transition is that transmission is the act of transmitting, eg data or electric power while transition is the process of change from one form, state, style or place to another.

There is an energy barrier that separates the energy levels of the reactants and products. ... The energy barrier is known as Ea, the activation energy. The activation energy is distinct from the ΔG, or free energy difference between the reactants and products.

The activation energy (Ea), labeled ΔG‡ in Figure 2, is the energy difference between the reactants and the activated complex, also known as transition state. In a chemical reaction, the transition state is defined as the highest-energy state of the system.

Catabolic reactions break down complex chemicals into simpler ones and are associated with energy release. Anabolic processes build complex molecules out of simpler ones and require energy. ... The change in free energy of a reaction can be negative (releases energy, exergonic) or positive (consumes energy, endergonic).

Describe the difference between a reaction that occurs spontaneously and one that does not. Spontaneous chemical reactions release energy and use that energy to power itself; non-spontaneous chemical reactions need to absorb energy, which they can't absorb their own energy that they don't even have.

Transition metals and their compounds function as catalysts either because of their ability to change oxidation state or, in the case of the metals, to adsorb other substances on to their surface and activate them in the process.

There is a slight difference between the two terms. Oxidation state refers to the degree of oxidation of an atom in a molecule. In other words, the oxidation state is the charge of an atom if all bonds it formed were ionic bonds. ... Oxidation numbers are used in coordination complex chemistry.

Complex ions containing transition metals are usually coloured, whereas the similar ions from non-transition metals aren't. That suggests that the partly filled d orbitals must be involved in generating the colour in some way. Remember that transition metals are defined as having partly filled d orbitals.

What is the difference between an activated complex and an intermediate? ... The activated complex is an unstable (unobserved) structure corresponding to an energy maximum in the reaction profile. An intermediate is the chemical structure present at the transition state.

The distinction between stable and metastable equilibrium is generally that the stable equilibrium state is "truly unchanging", or unchanging given in- definite time, whereas the metastable state may be changing, but too slowly to be observed (see Quota- tions).

C-states are idle power saving states, in contrast to P-states, which are execution power saving states. During a P-state, the processor is still executing instructions, whereas during a C-state (other than C0), the processor is idle, meaning that nothing is executing.

Oxidation state is the charge of the central transition metal if all the ligands were removed. Coordination number is the total number of bonds or attachments between the central transition metal and its ligands.

The dissociation of water molecules into ions is bond breaking and is therefore an endothermic process (energy must be absorbed to break the bonds). Endothermic processes are favoured by an increase in temperature and so as the temperature rises the equilibrium moves further to the right hand side and Kw gets larger.

The muscle contraction cycle is triggered by calcium ions binding to the protein complex troponin, exposing the active-binding sites on the actin. ... ATP then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.

Key Points. Chemical reactions often involve changes in energy due to the breaking and formation of bonds. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic.

If the cofactor turns the enzyme on it can be called an activator. If the cofactor turns the enzyme off it can be called an non-competitive inhibitor. (Non-competitive because the cofactor doesn't compete with the substrate for binding to the active site.) These cofactors are often metal ions.
