The reaction rate decreases as the reaction progresses primarily due to the depletion of reactants; as they are consumed, there are fewer molecules available to collide and react. Additionally, the accumulation of products can create a reverse reaction that competes with the forward reaction, further slowing the rate. Factors such as changes in temperature or concentration can also influence the reaction rate as the system approaches equilibrium.

What happens to the rate of a reaction is the reaction progresses?
As a reaction progresses, the rate typically decreases over time. This is due to the depletion of reactants, which reduces their concentration and, consequently, the frequency of effective collisions between reactant molecules. Additionally, the formation of products can lead to changes in reaction conditions that further slow the rate. Eventually, the reaction may reach equilibrium, where the rates of the forward and reverse reactions are equal, and no net change occurs.
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 the rate of reaction does not remain constant?
The rate of a chemical reaction does not remain constant because it depends on various factors, such as the concentration of reactants, temperature, and the presence of catalysts. As the reaction progresses, the concentration of reactants decreases, leading to a reduction in the rate of reaction according to the rate laws. Additionally, changes in temperature can alter the kinetic energy of particles, influencing how frequently they collide and react. Therefore, the dynamic nature of these factors causes the rate of reaction to vary over time.
In a first-order reaction how does the rate change if the concentration of the reactant decreases to one-third its original value?
In a first-order reaction, the rate of reaction is directly proportional to the concentration of the reactant. If the concentration decreases to one-third of its original value, the rate of the reaction will also decrease to one-third. This is because the rate equation for a first-order reaction can be expressed as ( \text{Rate} = k[A] ), where ( k ) is the rate constant and ([A]) is the concentration of the reactant. Therefore, a decrease in concentration leads to a proportional decrease in the reaction rate.
What causes the reaction rate to decreases as the reaction progresses?
The concentration of the reactants decreases.
What happens to the rate of reaction as the reaction progresses?
The rate decreases as reactants are used up.
What happened to the rate of a reaction as the reaction progresses?
In general, and depending on the order of the reaction, the rate will decrease as the reaction progresses.
What causes the reaction rate to decrease as the reaction progresses?
The concentration of the reactants decreases.
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.
