How is the rate of reaction compared with the time the reaction is carried out?

The time it takes for a reaction to occur is a function of the reaction rate constant and the amount of reactants. However, how long it takes for a reaction of occur completely depends on the type of reaction it is -- what the order of the reaction is. A first or second order reaction reaction will occur much faster earlier on, but slows down significantly once the reactants are depleted. The rate of a zero order reaction is constants regardless of the concentration of the reactants.

∙ 9y agoRate of reaction is equal to ONE over the time in seconds. As the time of the reaction goes down, the rate goes up. It's like driving a car. As the rate of speed goes up, the time goes down as the time goes up (takes longer to get there) the rate of speed must have gone down.

What is rate of time?
Rate in a reaction and rate used in calculus. dA/dt=rate.
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
What happens to the reaction rate as the reaction gets used up?
The reaction rate depends on the order of the reaction. In general (except for zero order), as the reaction progresses, the rate decreases with time.
How does agitation effect reaction rate?
Agitation affects reaction rate by increasing the amount of collisions the atoms make with one another, therefore speeding up the reaction rate.
What happens to the reaction rate as the reactants get used up in a reaction?
The rate of a reaction begins to decreases as reactant are used up
What is rate of time?
Rate in a reaction and rate used in calculus. dA/dt=rate.
What is the effect varying the concentration on the rate of reaction time?
Increasing the concentration of the reactants the rate of reaction increase.
How does the amount of time given affect the rate of the enzymatic reaction?
it will increase the time of the chemical reaction
Are reaction time and temperature directly proportional?
temperature is proportional to 1/time taken for reaction to complete (rate of reaction)
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
What happens If you decrease rate of chemical reaction?
The time the reaction takes increases.
What is faster a pulse rate or a reaction time?
A pulse rate because in a reaction u have to no what is going on so it takes longer then a pulse rate!!!!! X3
When giving the rate of a chemical reaction why would it be significant to know that the reaction rate is an average reaction rate?
Reaction rates are dependent on the concentration of reactants. As a reaction proceeds, the reactants are used up and thus their concentration is lowered. THis means that the maximum rate of reaction will be at or immediately after time zero, when the reaction is only just begun, and the minimum will be when one or more of the reactants' concentrations have reached zero. Thus, any rate stated for the reaction would only hold for a specific time in the reaction progress and cannot be extrapolated to cover all of that progress. So a mean rate of reaction must be used; this can tell a person, when combined with either the time of beginning, time of ending, or the initial concentrations, what any of the others were for the reaction in question. This is impossible to do if given a specific rate and the time it applied to; you cannot calculate any new information from just those two data.
Where does reaction time come from in the body?
Reaction time in the body comes from the brain and the nerves. The brain sends signals to the body which are carried by the nerves.
What happens to the reaction rate as the reaction gets used up?
The reaction rate depends on the order of the reaction. In general (except for zero order), as the reaction progresses, the rate decreases with time.
What is one physiological factor in reaction time?
any one of these: age,reaction time decreases with age gender, males usually has higher reaction rate, body temperature (higher body temperature=higher reaction rate)
How is the rate of reaction affected when the temperature increases?
As the temperature increases, the reaction time decreases.
