Reaction rates portfolio 3
WebThe rate of a chemical reaction is defined as the rate of change in concentration of a reactant or product divided by its coefficient from the balanced equation. A negative sign is used with rates of change of reactants and a positive sign with those of products, ensuring that the reaction rate is always a positive quantity. http://wwwresearch.sens.buffalo.edu/karetext/unit_04/learning/04_Info.pdf

http://pressbooks-dev.oer.hawaii.edu/chemistry/chapter/factors-affecting-reaction-rates/ WebUsually reactions speed up with increasing temperature ("100C rise doubles rate"). Physical state of reactants. Powders react faster than blocks - greater surface area and since the reaction occurs at the surface we get a faster rate. The presence (and concentration/physical form) of a catalyst (or inhibitor).
WebThe relation between the reaction rates expressed in terms of nitrogen production and ammonia consumption, for example, is: − Δmol NH 3 Δ t × 1 mol N 2 2 mol NH 3 = Δmol N 2 Δ t This may be represented in an abbreviated format by omitting the units of the stoichiometric factor: − 1 2 Δmol NH 3 Δ t = Δmol N 2 Δ t
