Because radioactive substances have half lives. This decreases the radioactivity in the substance.

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.


What is a material that slows down the rate of a chemical re action?

A catalyst is a material that speeds up a chemical reaction by providing an alternative pathway with lower activation energy. Alternatively, an inhibitor is a material that slows down a chemical reaction by blocking the active sites on the reactant molecules, preventing them from coming together or reacting.


If the amount of oxygen reaching the log is reduced what happens to the rate of this chemical reaction?

The rate of the chemical reaction will decrease because oxygen is one of the reactants required for the reaction to occur. With less oxygen available, the reaction will proceed at a slower pace.


What parameter involved in a chemical reaction will change with the addition of a catalyst?

The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.


What is the effect on the rate of a chemical reaction when the concnetration of a reactant is decreased?

Decreasing the concentration of a reactant will typically decrease the rate of a chemical reaction, as there are fewer reactant molecules available to collide and form products. This is in line with the rate law, which often shows a direct relationship between reactant concentration and reaction rate.

What would most likely result in the greatest decrease in the rate of a chemical reaction?

Decreasing the temperature or changing the concentration of the reactants would most likely result in the greatest decrease in the rate of a chemical reaction. These changes affect the collision frequency and energy of the reacting molecules, slowing down the overall reaction rate.

Does increasing the surface area increase or decrease the rate of a chemical reaction?

It will increase the rate of the reaction because more particles will be exposed and they will be able to react.This decreases the time to react.


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.
