According to earlier theory: The rate of radioactive decay can never be changed.But conflicting claims have recently appeared. Claims about how temperature appears to have an effect on the decay rate of some elements. The distance from the sun appears to have an effect as well.

What leads to the increase in the rate of a chemical reaction?
Many things lead to an increase in the rate of chemical reactions. These factors include: - Addition of Catalysts - Light (only in some reactions) - Increase in temperature - Increase in Pressure - Increase in amount of reactants
What change will most likely increase the rate of a chemical reaction?
Factors which can increase the rate of a chemical reaction:- temperature- pressure- concentration of reactants- stirring- if solids are involved the dimension of particles is important- the type of reaction- the order of reaction- presence of catalysts- influence of external factorsetc.
Describe the factors which affect chemical reaction rates?
The factors that change the reaction rates of chemical reactions are: 1)temperature 2)concentration 3)pressure 4)physical state 5)a catalyst
A sign that a chemical reaction is taking place is release of energy in the form of?
Most common chemical reactions are exothermic. This means that when the reaction occurs, they release heat. Some reactions are endothermic, which means they absorb heat.
How does increasing pressure affect the reaction rate?
The concentration of reactants is changed.
What are the 5 factors that can affect the rate of chemical reactions?
5 factors that can affect the rate of chemical reactions are temperature, pressure, concentration, stirring, catalysts.
How was gas formed beneath land?
These gases are formed by chemical reactions at high temperature and pressure.
Does the rate of radioactive decay slow by extreme cooling?
No, radioactive decay isn't affected by anything - temperature or pressure because it isn't a chemical or physical reaction.
Are chemical reactions affected by temperature pressure or catalysts?
They can be affected by all three together or each alone.
What are four ways that a chemist can control the rates of chemical reactions?
By changing concentration, temperature; pressure and volume (in the case of gases).
What are four ways chemists can control the rates of chemical reactions?
Varying the following parameters:- temperature- pressure- concentraton- stirring
What are different factors that affect the rates of chemical reactions?
Some different factors that affect the rates of chemical reactions include whether or not a catalyst is present, the concentration of the reactants, temperature of the reactants, & pressure in the case of gas phase reactions.
Which feedback mechanisms maintain equilibrium of systems like turgor pressure temperature and chemical reactions?
both negative and positive feedback
What can change the speed at which chemical reactions take place?
Enzymes EDIT from a different person: No! Catalysts, Temperature, Pressure, Concentration, Surface Area.
What are the three ways discussed in our lessons that chemists can control the rates of chemical reactions?
The reaction rate is dependet on temperature, pressure and reactants concentration.
What leads to the increase in the rate of a chemical reaction?
Many things lead to an increase in the rate of chemical reactions. These factors include: - Addition of Catalysts - Light (only in some reactions) - Increase in temperature - Increase in Pressure - Increase in amount of reactants
What are the characteristics of physical reactions?
For example temperature and pressure.
