What economic change was spurred technology?
No
Why does technology change supply?
Lowers production cost
What is the practical application of techniques and knowledge called?
Technology
What causes technology supply curve to shift?
a change in amount of goods available
Does a change in producers' technology lead to a movement along the supply curve or a shift in the supply curve?
Changes in a producer's technology can lead to a SHIFT in the supply curve.
What is the factor that is responsible for a change in some other factor called?
Catalyst?
Which does a catalyst not change?
Catalyst is not a reactant.
A substance which helps make a chemical change happen but is not changed itself in the process is called an?
The answer is catalyst
What is a substance which helps make a chemical change happen but is not changed itself in the process is called?
Catalyst: a substance which speeds up a chemical change or enables the change to take place at a lower tempature, and is not changed or used up in the reaction.
What substance increases the rate of a reaction but is not itself changed by the reaction?
It's called a catalyst. A catalyst is present during a chemical reaction but does not participate as a reactant or product. A catalyst lowers the reaction's activation energy, making the reaction easier to happen. In the equation for a chemical reaction, the catalyst's formula appears in small notation above the "yield" arrow (format won't let me show you an example.) An example of a catalyst is potassium iodide (KI) speeding up the decomposition of hydrogen peroxide (H2O2).
What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
Can a catalyst change rate of reaction equilibrium position or both?
A catalyst cannot change the equilibrium position. However, it can change its rate.
How does catalyst effect chemical change?
A catalyst alters the rate of a chemical reaction.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What is a substance that speeds up a reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction.
What is a A substance that speeds up a chemical reaction without being permanently changed itself?
This is a catalyst. A catalyst doesn't get destroyed during the reaction. Rather it's more of a reaction site where two substances can combine. One example of a catalyst is amyl alcohol, which can be used to produce pure potassium metal. However, it's destroyed during the process if there are impurities in the reaction because it's consumed in other reactions. Other examples of catalysts include catalase, platinum, and manganese(IV) oxide.
