  2. Element–reactant–product table - Wikipedia

    en.wikipedia.org/wiki/Element–reactant...

    From this table we see that the number of hydrogen and chlorine atoms on the product's side are twice the number of atoms on the reactant's side. Therefore, we add the coefficient "2" in front of the HCl on the products side, to get the equation to look like this:

  3. Schreinemaker's analysis - Wikipedia

    en.wikipedia.org/wiki/Schreinemaker's_analysis

    All reactants and products are stable in the field where the reaction plots. The absent phase is unstable where the reaction plots. Complex reactions (high number of participating phases) usually lie within bounding, simple reactions defining the phase stability region. The simplest divariant region usually contains the most metastable extensions.

  4. Conversion (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Conversion_(chemistry)

    Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...

    For such applications, must be incorporated in an expression that includes both the system and its surroundings: = + Via additional steps this expression becomes the equation of Gibbs free energy change for reactants and products in the system at the constant pressure and temperature : = where is the enthalpy change and is the entropy change.

  6. Reagent - Wikipedia

    en.wikipedia.org/wiki/Reagent

    Reagents, such as sulfur (pictured), are the starting materials used in chemical reactions.. In chemistry, a reagent (/ r i ˈ eɪ dʒ ən t / ree-AY-jənt) or analytical reagent is a substance or compound added to a system to cause a chemical reaction, or test if one occurs. [1]

  7. Thermodynamic versus kinetic reaction control - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_versus...

    Under kinetic reaction control, one or both forward reactions leading to the possible products is significantly faster than the equilibration between the products. After reaction time t, the product ratio is the ratio of rate constants k and thus a function of the difference in activation energies E a or ΔG ‡:

  9. Reaction step - Wikipedia

    en.wikipedia.org/wiki/Reaction_step

    In chemistry, a reaction step of a chemical reaction is defined as: "An elementary reaction, constituting one of the stages of a stepwise reaction in which a reaction intermediate (or, for the first step, the reactants) is converted into the next reaction intermediate (or, for the last step, the products) in the sequence of intermediates between reactants and products".
