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.

In a first order chemical reaction the velocity of the reaction is proportional to the while in a zero order reaction the velocity of the reaction is proportional to the .?
In a first-order chemical reaction, the velocity of the reaction is proportional to the concentration of the reactant. In contrast, in a zero-order reaction, the velocity of the reaction is independent of the concentration of the reactant and remains constant over time.
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 unit of first order reaction?
A zero-order reaction is a reaction that proceeds at a rate that is independent of reactant concentration. Typically with increasing or decreasing reactants
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 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.
In a first order chemical reaction the velocity of the reaction is proportional to the while in a zero order reaction the velocity of the reaction is proportional to the .?
In a first-order chemical reaction, the velocity of the reaction is proportional to the concentration of the reactant. In contrast, in a zero-order reaction, the velocity of the reaction is independent of the concentration of the reactant and remains constant over time.
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.
How can one determine the order of reaction from a graph?
To determine the order of reaction from a graph, you can look at the slope of the graph. If the graph is linear and the slope is 1, the reaction is first order. If the slope is 2, the reaction is second order. If the slope is 0, the reaction is zero order.
If you double a concentration of a reactant then the rate of the reaction doubled The order with respect to the reactant is?
The reaction is first order with respect to the reactant. In a first-order reaction, the rate is directly proportional to the concentration of the reactant. Doubling the concentration of a reactant will result in a doubling of the reaction rate.
What is the first-order reaction formula used to determine the rate of a chemical reaction?
The first-order reaction formula used to determine the rate of a chemical reaction is: Rate kA, where Rate is the reaction rate, k is the rate constant, and A is the concentration of the reactant.
What is the rate law expression for a first-order reaction?
The rate law expression for a first-order reaction is: Rate kA, where Rate is the reaction rate, k is the rate constant, and A is the concentration of the reactant.
What is the rate constant for this first-order reaction?
The rate constant for a first-order reaction is a constant value that determines how quickly the reaction occurs. It is denoted by the symbol "k" and is specific to each reaction. The rate constant can be calculated by using experimental data from the reaction.
What is the unit of first order reaction?
A zero-order reaction is a reaction that proceeds at a rate that is independent of reactant concentration. Typically with increasing or decreasing reactants
What is the order of the reaction with respect to the concentration of a?
The order of the reaction with respect to the concentration of A refers to how the rate of the reaction changes with changes in the concentration of A. It can be zero order, first order, second order, etc., depending on how the rate is affected by the concentration of A.
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.
