How is the effect of concentration changes on the reaction rate seen in the rate law?
The exponents determine how much concentration changes affect the reaction rate
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.
How is the effect of concentration changes on the reaction seen in the rate law?
Changes in concentration affect the rate of reaction by impacting the rate constant, k, in the rate law equation. Increasing reactant concentrations often leads to a higher rate of reaction, while decreasing concentrations can slow the reaction down. The rate law shows how the rate is related to the concentrations of reactants.
What subsequent experiment might the chemist want to conduct to build on her experiment?
The chemist could investigate the effect of different solvents on the rate of reaction to determine if solvent polarity plays a role. She could also vary the concentration of the reactants to explore how it influences the rate of reaction. Additionally, she could study the effect of temperature on the reaction rate to understand how kinetic energy affects the rate of the reaction.
Does the mass of a solid reactant affect the reaction rate?
The mass of a solid reactant typically does not directly affect the reaction rate, as it is the surface area of the solid that usually plays a more critical role in determining the rate of reaction. However, in some cases, a higher mass of solid reactant may lead to longer mixing times, which can indirectly affect the reaction rate.
How does mixing increase the rate of a reaction?
Mixing increases the rate of a reaction by ensuring that reactant molecules come into contact with one another more frequently. This leads to a higher frequency of successful collisions and an increase in the reaction rate. In essence, mixing helps to distribute reactants evenly and promote efficient reactions.
What effect does the concentration on reactants have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
What effect does the concentrate of reactants have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
What effect temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
What effect does the concentration of reactants have on the rate of reaction?
increasing the concentration increases the rate of the reaction
What effect of concentration of reactants have on the rate of a reaction?
increasing the concentration increases the rate of the 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.
What effect does catalyst on a reaction?
A catalyst speeds up the rate of a reaction.
What has no effect on the rate of an enzyme-catalyzed reaction?
Enzyme concentration has no effect on the rate of an enzyme-catalyzed reaction after reaching a saturation point where all enzyme active sites are occupied. At this point, adding more enzyme will not increase the reaction rate further.
What effect does a catalyst having a reaction?
A catalyst speeds up the rate of a reaction.
Does temperature effect the rate of chemical reaction?
yes.
