Why is it that the reaction times to impaired drivers often doubles in response to situations on the road?
Your response time to a situation is determined by your ability to recognize a situation and in reflexes, in short a cognitive response followed by a motoric response. Decreased visibility and lessened ability to retain concentration probably account for the increased response time of impaired drivers.

How does temperature in a luminol reaction affect light produced?
If the temperature of the glow stick (chemiluminescence) is warmer, it releases a brighter glow and has a shorter reaction time. If the temperature of the glow stick is colder, it releases a dimmer glow but has a longer reaction time. Lower temperatures slow reaction rates and release less light intensity then higher temperatures.
What is the application of PCR in biotechnology?
Polymerase chain Reaction is used to make copies of DNA (gene) using Taq polymerase enzyme. This is a method in which we put the DNA and four nucleotides along with primer and enzyme in the machine. It is computer operated machine and we set the loop for 15 minutes . Each cycle doubles the DNA. DNA obtained in this machine need not to be extracted because it is pure and same type. It is also called as Poeples choice reaction
Is it true that the temperature of a sample of steam increases from 100 to 200. The average kinetic energy of its particles doubles?
Yes, it is true. The average kinetic energy of gas particles is directly proportional to their temperature according to the kinetic theory of gases. So, when the temperature doubles from 100 to 200, the average kinetic energy of the steam particles also doubles.
A popalation of bacteria that doubles its size every 20 minutes exhibits growth?
Yes it exhibits growth
Is it true that Photosynthesis continues to increase with temperature?
YesIt is affected by enzymes.Reaction rate of enzymes affected by temperature. It incrase upto 60C ,then decrease due to denaturization
How would increasing the temperature affect the rate of a reaction?
Doubles it
What rough relationship can be infer between temperature and rate of reaction?
reaction rate doubles with every 10 K temperature change
How can one determine the order of a reaction from a table?
To determine the order of a reaction from a table, you can look at how the rate of the reaction changes with the concentration of reactants. If doubling the concentration of a reactant doubles the rate, the reaction is first order with respect to that reactant. If doubling the concentration quadruples the rate, the reaction is second order. And if doubling the concentration increases the rate by a factor of eight, the reaction is third order.
How can one determine the reaction order from a table of experimental data?
To determine the reaction order from a table of experimental data, you can plot the concentration of the reactant versus time for each experiment. The reaction order is determined by the slope of the line on the graph. If the slope is constant, the reaction is first order. If the slope doubles, the reaction is second order. If the slope triples, the reaction is third order.
How does temperature affect the rate of a chemical change?
Changing temperatures has a dramatic affect on the rate of chemical reaction. As an example for every 10 degrees you raise the environment the reaction doubles (to a certain degree)
How can one determine the order of reaction by utilizing concentration and time data?
To determine the order of reaction using concentration and time data, one can plot the natural logarithm of the concentration of the reactant against time. The slope of the resulting graph will indicate the order of the reaction. If the slope is constant, the reaction is first order; if the slope doubles, the reaction is second order; and if the slope triples, the reaction is third order.
How does the scoring system work in doubles tennis tie break situations?
In doubles tennis tie break situations, the scoring system works the same as in singles. The first team to reach seven points with a margin of two points wins the tie break. Each player on the serving team serves for one point, alternating between teams every two points.
How does the reaction temperature affect the rate of a chemical reaction?
Generally, an increase in reaction temperature leads to a higher rate of reaction. This is due to the fact that higher temperatures provide reactant molecules with more kinetic energy, leading to more frequent and energetic collisions between them, which in turn increases the chances of successful collisions and reaction. However, extremely high temperatures can also lead to the degradation of reactants or products, affecting the overall reaction rate.
When can you double a hand in bridge card game?
These days most doubles are used for "takeout", which simply tells asks the doubler's partner to choose from any unbid suit. There are situations when doubles become strictly for penalties, to increase the score received when the opponents fail in their contract. There is no universal agreement on which doubles are for penalty and which for takeout - this is a topic for each partnership to discuss.
How can the effect of heat on a reaction be determined?
heat is treated as a reactant or product
What would happen to the rate of a reaction with rate law kNO2H2 if the concentration of NO were doubled?
The rate would be four times larger
How is rate of a chemical reaction usually expressed?
Rates of reaction can be expressed depending upon their order.For example say you have a reaction between two chemicals and the initial rate for that reaction is known :-when:-The concentration of one of the reactants is doubled and the other reactants concentration remains the same and the overall rate of reaction does not change - reaction is zero orderwith respect to chemical which was doubled.The concentration of one of the reactants is doubled and other reactants concentration remains the same and the overall rate of reaction doubles - reaction is first order with respect to chemical which was doubled.The concentration of one of the reactants is doubled and other reactants concentration remains the same and the overall rate of reaction quadruples - reaction is second order with respect to chemical which was doubled.Zero Orderrate = kFirst Orderrate = k [A] (reaction is 1st order with respect to [A] and 1st order overall)Second Orderrate = k [A][B] (reaction is first order with respect to [A] and first order with respect to[B], reaction is second order overall)rate = k [A]2 (reaction is second order with respect to [A] and second order overall)Orders are simply added together in order to determine the overall order of reaction :-rate = k [A][B][C] would be third order overall and first order with respect to each of the reactantsThere are other orders of reaction, for example 2 and 3 quarter orders and third order reactions, but these are a little more complex.
