What factors affect the rate at which Bunsen burner heats water in a beaker?
tempareture ,nature of the substance and the controller of the bunsen burner
Why is heat often added to a chemical reaction performed in a laboratory?
By heating you are adding energy!!! Energy is needed to start a reaction ; it is called ther Activation Energy'. If you use a Bunsen Burner in the lab. to heat reactants.. Then some of the heat is going in (endothermic) to start the reaction. The heat you feel from the Bunsen Burner is waste energy; it is not going in to start the reaction. Remember ; Bond breaking is endothermic (heat/energy to go in ) Bond making is exothermic ( heat / energy is given off) ;the reaction might feel warm., without any applied energy. Other forms of energy that can be used in achemical reaction are ;- Electricity, Light, Sound, and Mechanical (stirring).
What describes a reaction that reaches equilibrium?
The product and reactants reach a final, unchanging level.
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.
Could heat increase the rate of reaction?
if reaction is exothermic then on heating rate of reaction wil be low,and if reaction is endothermic then rate of reaction wil be high on heating
What factors affect the rate at which Bunsen burner heats water in a beaker?
tempareture ,nature of the substance and the controller of the bunsen burner
How does the control rod affect the rate of reaction in the nuclear reactor?
A control rod is made of a neutron absorbing material. Boron is common. When the control rod is withdrawn (pulled out) of the reactor, the fission reaction rate increases. When that control rod is inserted, the reaction rate decreases. There are other factors that control the reaction rate, but the rods can be considered as the way to start up or shut down the reactor by pulling or inserting them.
What is air hole in Bunsen burner?
The function of a Bunsen burner chimney is that the natural gas draws air into the barrel as it passes the air intake opening.

Compare and contrast a catalyst and an inhibitor?
Catalysts increase the rate of reaction while Inhibitors decrease it. They both affect the rate of reaction, hence giving us more control over our reaction.
What factors control the rate of the reaction?
the main factors that control the rate of the reaction are: 1. The nature of the reactants. 2. The surface are exposed. 3. The concentrations 4. The temperature 5. Presence of a catalyst. 6. Presence of an inhibitor.
What is the function of the control rods in a power plant?
The control rod would have a tendency to absorb neutron which is the key for nuclear fission. So by inserting control rods such as Cadmium or Boron rods the reaction rate can be reduced. If we take off the rods the rate of reaction would increase.
Enzymes control this aspect of chemical reactions?
Enzymes as such do not control things directy. However, the rate of a biochemical reaction can be controlled by enzymes.
What measures of how fast reaction occurs?
The measure is the rate of reaction.
What is the speed at which a reaction occurs called?
The chemical term is reaction rate.
What would happen if the control rods were removed from the reactor core?
Typically the reaction rate increases.
Is another way to control the rate of a reaction to change the activation energy needed?
Adding a catalyst.
