What temperature change do you think would be required to increase or decrease the reaction time by a factor of 2?
all chemical reaction has to be thought of to be there
What it will change adding a catalyst to a chemical reaction?
It will increase or decrease the speed of the chemical reaction.
How do changes in energy and temperature influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
How an increase in temperature change the rate constant of a chemical reaction?
yes ofcourse!
What causes an increase in the rate of a chemical reaction between 2 liquids?
Increasing the temperature will increase the reaction rate, as will finding a suitable catalyst.
Why does the temperature increase and decrease during neutralization?
Neutralization is an exothermic chemical reaction and thus heat is given out.

What it will change adding a catalyst to a chemical reaction?
It will increase or decrease the speed of the chemical reaction.
Do Enzymes increase or decrease the Activation Energy of a Chemical Reaction?
decrease
What two types of energy change can occur in a chemical reation?
Two types of energy change that can occur in a chemical reaction are endothermic or exothermic. An exothermic reaction causes an increase in temperature and an endothermic reaction causes a decrease in temperature.
What leads to an increase in the rate of a chemical reaction?
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
What is the relationship between an enzyme temperature and the chemical reaction in which the enzyme is invoved?
Rate increase with temperature up to 40 celcius.But it decrease to 60 celcius and stops after.
Which of the following tends to increase the rate of a chemical reaction?
Increasing the temperature of the reactants can increase the rate of the chemical reaction.
A factor that slows down a chemical reaction?
A decrease in temperature.
An increase in temperature will cause the rate of a chemical reaction to?
Increasing the temperature the dissolving rate increase.
How might a thermometer help you decide if there was any chemical change on mixing iron and charcoal?
For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.
What effects does temperature have on chemical changes?
Generally the speed of reaction increase when the temperature is increased.
