What effects does the concentration of reactions have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
What is the relationship between concentration and reaction rate?
In general (but not always), the reaction rate will increase with increasing concentrations. If the reaction is zero order with respect to that substance, then the rate will not change.
How does the concentration of a pure liquid change throughout the course of a reaction?
The concentration of a pure liquid does not change throughout the course of a reaction since it is not involved in the reaction itself. The concentration of a pure liquid remains constant because its molecules do not participate in the reaction.
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.
How do you calculate the rate of reaction?
The formula is:r = k(T) · [A]n'· [B]m' where:- r is the rate of reaction- k is the rate constant- [A] and [B] are the concentrations of the reactants- n' and m' are the reaction orders- T is the temperature
What effects does the concentration of reactions have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
Does the rate constant change with concentration in a chemical reaction?
Yes, the rate constant can change with concentration in a chemical reaction.
What effect does the concentration of reactants have on the rate of speed?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
How is the effect on concentration change on the reaction rate seen in the rate law?
The exponents determine how much concentration changes affect the reaction rate

There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
How do you calculate the initial rate of a reaction?
The initial rate of a reaction is calculated by measuring the change in concentration of reactants over time at the beginning of the reaction. This is done by dividing the change in concentration by the change in time. The initial rate is typically expressed in units of concentration per unit time.
What is the relationship between concentration and reaction rate?
In general (but not always), the reaction rate will increase with increasing concentrations. If the reaction is zero order with respect to that substance, then the rate will not change.
How do you calculate the initial rate of reaction in a chemical reaction?
To calculate the initial rate of reaction in a chemical reaction, you measure the change in concentration of a reactant over a specific time interval at the beginning of the reaction. This change in concentration is then divided by the time interval to determine the initial rate of reaction.
How can one calculate the initial rate of reaction from concentration?
To calculate the initial rate of reaction from concentration, you can use the rate equation. This equation relates the rate of reaction to the concentrations of the reactants. By measuring the change in concentration of the reactants over a short period of time at the beginning of the reaction, you can determine the initial rate of reaction.
