Figure 6:Reaction Coordinate Diagrams showing reactions with 0, 1 and 2 intermediates: The double-headed arrow shows the first, second and third step in each reaction coordinate diagram. In all three of these reactions the first step is the slow step because the activation energy from the reactants to the transition state is the highest.
ACS settings should be used for both structures and reaction schemes. These settings are normally available as templates in chemical drawing programs. Use sans-serif fonts like Arial. Indexes used for labelling must be superscripted: R 1-CH 2-R 2 (not R 1-CH 2-R 2) Do not include English text in images: this prevents their reuse in other languages.
N-Methylaniline (NMA) is an aniline derivative.It is an organic compound with the chemical formula C 6 H 5 NH(CH 3).The substance is a colorless viscous liquid, Samples turn brown when exposed to air.
The collective variables reduce many variables to a lower-dimensional set of variables, that still describe the crucial characteristics of the system. Many collective variables than span the reaction coordinate with a continuous function ξ: ξ(t) = ξ{CV i (t)} with j ∈ N. [2] An example is the complexation of two molecules.
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

N-Ethyl-N-(2-chloroethyl)aniline is the organic compound with the formula C 6 H 5 N(Et)(CH 2 CH 2 Cl) (Et = ethyl). It is a low-melting colorless solid that is an alkylating agent . The compound is a precursor to several cationic azo dyes via reaction of the chloroethyl group with tertiary amines or pyridine followed by azo coupling .
In the breakdown of a compound into its constituent parts, the generalized reaction for chemical decomposition is: AB → A + B (AB represents the reactant that begins the reaction, and A and B represent the products of the reaction) An example is the electrolysis of water to the gases hydrogen and oxygen: 2 H 2 O(l) → 2 H 2 (g) + O 2 (g)
The Diels-Alder reaction is perhaps the most important and commonly taught cycloaddition reaction. Formally it is a [4+2] cycloaddition reaction and exists in a huge range of forms, including the inverse electron-demand Diels–Alder reaction, hexadehydro Diels–Alder reaction and the related alkyne trimerisation.
