How is the rate of reaction compared with the time the reaction is carried out?
The time it takes for a reaction to occur is a function of the reaction rate constant and the amount of reactants. However, how long it takes for a reaction of occur completely depends on the type of reaction it is -- what the order of the reaction is. A first or second order reaction reaction will occur much faster earlier on, but slows down significantly once the reactants are depleted. The rate of a zero order reaction is constants regardless of the concentration of the reactants.
How can the rate law for a a chemical reaction be used to determine an instantaneous reaction rate?
The rate law for a chemical reaction expresses how the rate of the reaction depends on the concentration of reactants. By plugging in the instantaneous concentrations of the reactants into the rate law equation, we can calculate the instantaneous reaction rate at a specific moment in time.
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.
What does the rate law use to determine the rate of reaction?
The rate of a reaction is calculated using the concentrations of reactants.
What is the value and unit of the rate constant for this reaction?
The value and unit of the rate constant for a reaction represent how fast the reaction occurs. The rate constant is typically denoted by the symbol "k" and its unit depends on the overall order of the reaction. The unit of the rate constant can be determined by the reaction rate equation.
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.
What is the rate of reaction between organic and inorganic compound?
This depends on each chemical reaction.
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.
What is the zero order reaction rate law and how does it determine the rate of a chemical reaction?
The zero order reaction rate law states that the rate of a chemical reaction is independent of the concentration of the reactants. This means that the rate of the reaction remains constant over time. The rate of the reaction is determined solely by the rate constant, which is specific to each reaction. This rate law is expressed as: Rate k, where k is the rate constant.
What effect does the concentration of reactants have on the the rate of a reaction?
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.
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.
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.
