The unit of a first order reaction rate constant is time^-1. This means that the rate constant k has units of 1/time, such as s^-1.

What is the reaction order of the decomposition of nitrogen pentoxide?
The decomposition of nitrogen pentoxide is a first-order reaction. This means that the rate of the reaction is directly proportional to the concentration of nitrogen pentoxide raised to the power of 1.
What is The order of reaction for which unit of rate and rate constant is same?
In a zero order overall process, the rate and rate constant will be the same. (Reaction order is an exponent, and if that exponent is "0" then the value is "1" and will cancel out.)
What is first order kinetics?
First-order kinetics refers to a reaction in which the rate is directly proportional to the concentration of one reactant. This means that the reaction proceeds at a speed determined by the concentration of the reactant involved, leading to a constant half-life. The rate constant for a first-order reaction has units of 1/time.
Why first order reaction never completes?
A first-order reaction will never be completed because the reaction rate depends only on the concentration of one reactant. As the reaction progresses and the reactant is consumed, the concentration of the reactant decreases, causing the reaction rate to also decrease. This gradual decrease in reaction rate means that the reaction will continue indefinitely, given enough time.
Why radioactivity is considered as a first order reaction?
Radioactivity is the disintegration of the substance by its own. This means disintegration depends only on one reactant concentration i.e.,on itself. So this is a first order reaction.
What is the reaction order of the decomposition of nitrogen pentoxide?
The decomposition of nitrogen pentoxide is a first-order reaction. This means that the rate of the reaction is directly proportional to the concentration of nitrogen pentoxide raised to the power of 1.
How do you prove graphically that a reaction is first order?
To prove graphically that a reaction is first order, you would plot the natural log of the concentration of the reactant versus time. If the resulting graph is linear, then the reaction is first order. This linear relationship indicates that the rate of the reaction is directly proportional to the concentration of the reactant.
Is hydrochloric acid and calcium carbonate a first order reaction?
No, the reaction between hydrochloric acid and calcium carbonate is not a first order reaction. It is a decomposition reaction where the rate of reaction will not be constant as the concentration of the reactants change over time.
What is The order of reaction for which unit of rate and rate constant is same?
In a zero order overall process, the rate and rate constant will be the same. (Reaction order is an exponent, and if that exponent is "0" then the value is "1" and will cancel out.)
75 of a first order reaction was found to complete in 32 minutes When will 50 of the same reaction complete?
If 75 of a first order reaction was complete in 32 minutes then 50 of the same reaction will complete in 21 minutes 18 seconds.
How is order of reaction determined graphically?
The order of a reaction can be determined graphically by analyzing concentration versus time data. For a first-order reaction, plotting ln(concentration) versus time should give a straight line. For a second-order reaction, plotting 1/concentration versus time should give a straight line. The slope of the line in these graphs reveals the order of the reaction.
What is first order kinetics?
First-order kinetics refers to a reaction in which the rate is directly proportional to the concentration of one reactant. This means that the reaction proceeds at a speed determined by the concentration of the reactant involved, leading to a constant half-life. The rate constant for a first-order reaction has units of 1/time.
What is first order cycle reversible reaction?
A first-order cycle reversible reaction is a chemical reaction where the rate of the reaction is directly proportional to the concentration of only one reactant. This type of reaction can proceed in both the forward and reverse directions. The rate of the reaction changes depending on the concentration of the reactant involved.
What is meant by the order of a chemical reaction?
The order of a chemical reaction refers to the mathematical relationship between the rate of the reaction and the concentration of reactants. It is determined by experimentally measuring how changes in reactant concentrations affect the rate of the reaction. The order can be zero, first, second, or higher order, indicating how the rate of the reaction changes with the concentration of reactants.
X is second order and Y is first order X plus Y-- XY Does the reaction occur in a single step in which X and Y collide?
Yes, the reaction occurs in the step where X and Y collide. The first step is part of an elementary reaction and in an elementary reaction, the order is nothing but the coefficient in front of the reactant.
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.
Why radioactivity is considered as a first order reaction?
Radioactivity is the disintegration of the substance by its own. This means disintegration depends only on one reactant concentration i.e.,on itself. So this is a first order reaction.
