What does not affect the half-life or a radioactive substance?
The temperature The total amount of the substance The addition of a catalyst ~
What is a substance that speeds up a chemical process?
catalyst-by lowering activation energy
What is a substance that speeds up a reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction.
Which of the following is not true of a catalyst?
A catalyst is a material which make possible a chemical reaction, improve the rate of reaction, increases the yield of the reaction; a catalyst doesn't react with reactants/products.
What effect does a promoter catalyst have on the position of the equilibrium?
By definition a catalyst cannot affect equilibrium because although a catalyst can speed up a chemical reaction, it cannot change the thermodynamics of it, and equilibrium is determined solely by thermodynamics. A catalyst may help a system reach equilibrium more quickly, but it will not change it. One possible way a catalyst could affect equilibrium is by introducing a catalyst that affects a different reaction involving the substrate or products of the original reaction, but this would be cheating since the system would no longer be closed.
