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 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
Is it true that the temperature of a sample of steam increases from 100 to 200. The average kinetic energy of its particles doubles?
False
A popalation of bacteria that doubles its size every 20 minutes exhibits growth?
Yes it exhibits growth
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 does the reaction temperature affect the rate of a chemical reaction?
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)

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.
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
Is the rate of a chemical reaction dependent of temperature?
In general, as temperature rises, so does reaction rate. This is because the rate of reaction is dependent on the collision of the reacting molecules or atoms. As temperature rises, molecules or atoms respond with increased motion, increasing the collision rate, thus increasing the reaction rate.
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.
What can be done to temperature to increase the rate of chemical reaction?
Generally speaking, raising the temperature will encourage an increase in the rate of chemical reaction. Around room temperature, a general rule of thumb is that increasing the temperature 10 degrees Celsius doubles the rate of reaction. This is a very rough approximation; you can use something called the Arrhenius equation if you need more exact values. It's actually a little bit more complicated than that, because if the reaction is reversible then it also increases the rate of the reverse reaction, and there's a dependence on the activation energy, and increasing the temperature could make alternative reactions possible. But, to a first approximation: if you want a reaction to go faster, and temperature is the only thing you can change, raise the temperature.
Why is a chemical reaction rate doubled when the concentration of one reactant is doubled explain this in terms of collision theory?
Pretty simple, really. For any one "A" molecule, if there are twice as many of the other "B" molecule present then the odds of it colliding with one of them are twice as high. The same equations for effective collisions hold, so doubling the concentration doubles the reaction rate.
Can you have doubles play in tennis?
Yes. Mens Doubles, Ladies Doubles and Mixed Doubles are permitted forms of Doubles in Tennis.
Is it good to double down on a soft 17?
It is correct Basic Strategy to "Double" with a Soft 17 when the dealer's face up card is a 3, 4, 5, or 6. The specified situations cited above, present the player with a profitable situation, ergo one doubles their money at risk.
