what relationship exists between reaction time and reaction rate?
312491
The reaction rate is the change in the concentration of either the reactant or the product over a period of time. The concentration of A decreases with time, while the concentration of B increases with time.

Another way to think of it is that reactions rates are always positive and since k is a proportionality constant that relates some given concentration(s) (which are always positive) with the rate (also always positive), it's not possible for k to be negative.

The rate of a reaction, or stage in a reaction, is proportional to the reciprocal of the time taken. Rate α 1 time Rate is inversely proportional to time. Units: s-1, min-1 etc. Units: s, min etc.

The relationship between rate of reaction and concentration of substrate depends on the affinity of the enzyme for its substrate. This is usually expressed as the Km (Michaelis constant) of the enzyme, an inverse measure of affinity.

Increasing the temperature a reaction takes place at increases the rate of reaction. At higher temperatures, particles can collide more often and with more energy, which makes the reaction take place more quickly.

The average (median) reaction time is 215 milliseconds, according to the data collected so far. In addition to measuring your reaction time, this test is affected by the latency of your computer and monitor. ... While an average human reaction time may fall between 200-250ms, your computer could be adding 10-50ms on top.

Effect of increasing surface area on the rate of a reaction. As we increase the surface area of the reactants, we increase the rate of reaction. Increasing the surface area of a solid reactant exposes more of its particles to attack.

By increasing the enzyme concentration, the maximum reaction rate greatly increases. Conclusions: The rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.

Factors that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, the physical state of reactants and their dispersion, the solvent, and the presence of a catalyst.

Comparison between Dynamic and Static Equilibrium A reaction is at dynamic equilibrium if the rate of the forward reaction is equal to the rate of the reverse reaction. It is at static equilibrium if the reaction has occurred and the forward and reaction rates are both equal to 0.

It is integrated into every step an officer takes throughout their entire law enforcement career so having an understanding of it could be crucial to success. Studies have shown reaction is actually faster than action itself which creates confusion with the old saying, “Action is faster than reaction”.

A reaction is survival-oriented and on some level a defense mechanism. It might turn out okay but often a reaction is something you regret later. A response on the other hand usually comes more slowly. It's based on information from both the conscious mind and unconscious mind.

There is no such relationship. There is a relationship between frequency and wavelength, and it is inverse, with the product of frequency and wavelength giving the propagation speed in the medium. The amplitude, however, can be anything - it's an independent variable.

The Order of reaction refers to the relationship between the rate of a chemical reaction and the concentration of the species taking part in it. In order to obtain the reaction order, the rate expression (or the rate equation) of the reaction in question must be obtained.

['Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt.', 'The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.']

The mean fastest reaction time recorded by men was significantly faster than women (p<0.001). ... However, that sex difference in reaction time is likely an artifact caused by using the same force threshold in women as men, and it permits a woman to false start by up to 21 ms without penalty.

“The rate at which a substance reacts is directly proportional to its active mass and rate of a chemical reaction is directly proportional to product of active masses of reactants each raised to a power equal to corresponding stoichiometric coefficient appearing in the balanced chemical equation”.
