Some factors are: low temperature, low pressure, low concentration of reactants, no stirring, coarse particles, etc.

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.
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.
A catalyzed reaction will have a activation energy and this leads to a in the reaction rate. A) lower decrease B) lower increase C) higher decrease D) higher increase?

What would happen to the rate of a reaction with rate law rate equals k NO 2 H2 if the concentration of NO were halved?
It will decrease by half.
If the amount of oxygen reaching the log is reduced what happens to the rate of this chemical reaction?
The rate of the chemical reaction will decrease because oxygen is one of the reactants required for the reaction to occur. With less oxygen available, the reaction will proceed at a slower pace.
Which is a way that does not decrease the rate of a reaction?
decompision
What material slows down the rate of chemical reaction?
Inhibitor~a material used to decrease the rate of reaction
What happens to the reaction rate as the reactions get used up in a reaction?
The rate of the reaction begins to decrease as reactants are used up (apex)
What happens to the reaction rate as the reactants get used up in the reaction?
The rate of the reaction begins to decrease as reactants are used up (apex)
What causes the reaction rate to decrease as the reaction progress?
The concentration of the reactants decreases.
What would happen to the rate of a reaction with rate law rate k NO 2 H2 if the concentration of NO were halved?
If the concentration of NO is halved, the rate of the reaction will also be halved. This is because the rate of the reaction is directly proportional to the concentration of NO raised to the power of its coefficient in the rate law (in this case 1). So, halving the concentration of NO will result in a proportional decrease in the rate of the reaction.
A material used to decrease the rate of a reaction is called?
inhibitor
A material used to decrease the rate of a chemical reaction is what?
retardant
What would happen to the rate of a reaction with rate law rate k NO 2 H2 if the concentration of H2 were halved?
Halving the concentration of H2 will decrease the rate of the reaction, assuming it is a first-order reaction with respect to H2. Since the rate law is rate = k[NO]^2[H2], cutting the concentration of H2 in half will decrease the rate of the reaction by a factor of 0.5.
What would most likely result in the greatest decrease in the rate of a chemical reaction?
Decreasing the temperature or changing the concentration of the reactants would most likely result in the greatest decrease in the rate of a chemical reaction. These changes affect the collision frequency and energy of the reacting molecules, slowing down the overall reaction rate.
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.
