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 is the decrease in the concentration of reactants over time known as?
The decrease in the concentration of reactants over time is known as the reaction rate. This term refers to the speed at which reactants are converted into products in a chemical reaction. The reaction rate can be influenced by various factors, including temperature, concentration, and the presence of catalysts.
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.
How in terms of collision theory how a decrease in concentration can change the rate of a precipitation reaction?
Decrease in conc. means decrease in no. of molecules per unit volume. Since, molecules or atoms will less in number, the no. of colliding particles will be less. This will lead to decreased precipitation
Why does a reaction slow down with time?
The reactant concentrations decrease
What causes the reaction rate to decrease as the reaction progress?
The concentration of the reactants decreases.

The reaction rate can be influenced by various factors, including temperature, concentration, and the presence of catalysts.
Why does the reaction decrease as the reaction progresses?
There are fewer reactants left to collide.

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.
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 effects does the concentration of reactants have on the rate of the reaction?
increasing the concentration increases the rate of the reaction
Why does a reaction slow down time?
A reaction can slow down due to factors such as a decrease in reactant concentration, a decrease in temperature, or the presence of inhibitors that interfere with the reaction mechanism. These factors can reduce the frequency of successful collisions between reactant molecules, thus slowing down the rate of the reaction.
Why does a reaction slow down with time?
The reactant concentrations decrease
