Substrate concentration is directly proportional to rate of reaction because more enzymes are able to act on it but this happen only until all the active sites are covered than reaction rate becomes constant.
Changing the concentration of S2O8^2- ion in a reaction can affect the reaction rate. Increasing the concentration of S2O8^2- typically results in a faster reaction rate because there are more reactant particles available to collide and react. Conversely, decreasing the S2O8^2- concentration can slow down the reaction as there are fewer reactant particles available to collide.
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.
The limiting reagent (aka limiting reactant) is the substance which is completely used in a chemical reaction.
Chemical properties can only be determined by changing a substance.
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.
To determine the initial concentration of a substance in a chemical reaction, you can use the formula: initial concentration (final concentration) / (reaction coefficient). This involves knowing the final concentration of the substance and the reaction coefficient from the balanced chemical equation.
The yield of the reaction depends in this case only on the concentration of the limiting reactant.
Concentration per unit time, also known as rate of change of concentration, is a measure of how quickly the concentration of a substance is changing with respect to time. It indicates the speed at which a substance is being produced or consumed in a reaction or process. This can be calculated by dividing the change in concentration by the time interval over which the change occurred.
A titration reaction is a chemical technique used to determine the concentration of a substance in a solution. It involves the gradual addition of a known concentration of another substance, called the titrant, to the solution until a reaction is complete. The endpoint of the reaction is usually detected using an indicator or an instrument, allowing for the calculation of the concentration of the unknown substance.
When the amount of a substance changes, it can affect the concentration, density, and reactivity of the substance. In chemical reactions, changing the amount of a substance can also impact the equilibrium position and the rate of reaction. Additionally, changing the amount of a substance can influence its physical properties, such as melting point, boiling point, and solubility.
In a titration, a known concentration of a substance (titrant) is added to the unknown substance until a chemical reaction reaches completion. By measuring the volume of titrant required to reach a specific endpoint, the concentration of the unknown substance can be calculated using the stoichiometry of the reaction.
A reactant is a substance that participates in and changes during a reaction.
Changing the concentration of S2O8^2- ion in a reaction can affect the reaction rate. Increasing the concentration of S2O8^2- typically results in a faster reaction rate because there are more reactant particles available to collide and react. Conversely, decreasing the S2O8^2- concentration can slow down the reaction as there are fewer reactant particles available to collide.
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.
The spontaneity of a reaction can be reversed by changing the conditions such as temperature, pressure, or concentration of reactants, or by adding a catalyst.
Increasing the concentration of an acid would increase the rate and vigor of the reaction involving a metal such as magnesium.
The average rate of disappearance for a substance in a chemical reaction is the speed at which the substance is used up over time. It is calculated by dividing the change in concentration of the substance by the change in time.
