How is a reaction rate measured experimentally?
There are two ways people can measure the rate of reaction. People can measure how quickly the reactants are used up as they react to make products. Or people can measure the rate at which the products of the reaction are made.
What does the reaction rate say about the reaction?
It indicates how fast reactants become products.
How can a reaction generally be made to go more quickly?
Lowering the activation energy, Adding a cataylst
What is a reactent and products chemical reaction?
A reaction has two components with the reactant as an "ingredient," and the product is the end result. A combustion reaction as the reactants of O2 (oxygen) and CH4 (methane). Their product through the reaction CH4 + 2O2 is 2H2 (water) and C02 (carbon dioxide).
What ar five factors that affect the rate of a chemical reaction?
The rate of a Chemical reaction is affected by a number of factors, here are the commonly taught "Five factors of reaction rates":1-Nature of the Reactants (Based on the atomic structure, ie. the stability of the reactants vs. the stability of the proposed products)2-Ability of the Reactants to meet ( the state of the reactants: gases and liquids are more likely to react, AND the Surface area: powders have a greater surface area and therefore react quickly)3- Concentration of the Reactants (the higher the concentration, the more likely the reactants are able to meet and react, thus increasing the reaction rate)4- Temperature (the higher the temperature of the system, the faster the particles are moving (Kinetic Molecular Theory) and the faster they will collide, thus increasing the reaction rate)5- Presence of Catalysts (Catalysts increase the reaction rate by overcoming the activation energy. They work by decreasing the reaction barrier of the Rate determining step, which is the slowest step of a chemical reaction)Of course, there are other factors which affect the reaction rate of a given system, but these are the 5 commonly cited ones they teach you in high school. If you're interested, I'd suggest reading about Collision Theory and Transition State Theory.huifhyiusdyhtrfu0er8ut09o79retgvkghvvyhogiyhvoufysyo8yiySurface areaconcentrationcatalyststemperatureinhibitors

Which ways can be used to measure reaction rate?
It depends on the reaction. A hydrolysis reaction involving a color change can be measured spectrophotometrically using UV/Visible or Infrared spectroscopy. Gas Chromatography can also measure the appearance of products or disappearance of reactants versus time.
What does the reaction rate say about the reaction?
It indicates how fast reactants become products.
What is the difference between equilibriun and reaction rate?
Equilibrium is where the products and reactants are formed at equal rates. It is basically a two-way reaction. The reaction rate is how quickly the reaction takes place, or how quickly the products react to form the products.
What information does the rate constant give the rate law?
It tells how much the reaction rate is affected by concentrations.
How can a reaction generally be made to go more quickly?
Lowering the activation energy, Adding a cataylst
What is a reaction timer?
A reaction time is the a measure of how quickly an organism can respond to a stimulus. For example if someone hits you out of the blue you may have a slow reaction time because you have to take in what happen.
How does a catalyst change the rate of a chemical reaction?
Lowers the activation energy of a reaction, therefore speeding the reaction up.Catalysts speed up chemical reactions. They do not change the products or reactants of the reaction, and are not used up or consumed in the reaction. Biological catalysts are called enzymes. Catalysts lower the activation energy (or energy needed to start a reaction), and cause the reaction to occur more quickly.

How is an explosion created?
Explosions come in two types - deflagration and detonation. In deflagration the heat from the reaction quickly heats surrounding unreacted reactants causing the reaction to accelerate - producing more heat to accelerate the reaction even more, etc. Also with the rapid reaction, it compresses the gas around it further accelerating the reaction in the gas phase.In a detonation the reaction occurs so quickly that the reaction boundary outstrips the shockwave (which travels at sonic speed), compressing the material behind it as well as in front of it.Detonations are much more powerful than deflagrations.
What does it mean when are reaction is spontaneous?
The reaction happens by itself.
