A catalyst can speed up the rate of a given chemical reaction by lowering the activation energy required for the reaction to occur. However, the catalyst does not change the total free energy from reactants to products.

A pycnocline is a boundary between changing regions of which of the following properties?
Density
Name three weather conditions that change daily?
Meteorological and atmospheric conditions are dynamic, that is they are constantly changing. Three conditions that can change by the day are humidity, ambient air temperature and visibility.
Which of the following do the changing seasons have the most influence on?
The hibernation patterns of ground squirrels
What are three ways to increase the rate at which particular reaction proceeds?
There are three ways to increase the rate of a chemical reaction. One way is to increase the temperature of the reaction, which increases the rate of molecular collision. Another option is to add a catalyst to the reaction which chemically enables the rate of reaction. Lastly, increase the pressure in the reaction area, which increases the rate of molecular collisions.
What does a catalyst do to the rate of a chemical reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction without changing the substance. It does this by reducing the minimal reaction energy. A catalyst is not used up in a reaction therefore they last indefinitely.
What is a substance that speeds up the chemical reaction pernmanently changing?
Catalyst. Biological catalysts would be enzymes.
What is a substance that speeds up a chemical reaction with out changing permanently or being used up?
This is called a catalyst.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What might be an advantage of a single population of animals such as the Purple Gorilla having a very large amount of variability surrounding certain traits?
It increases the chance that some members of the population will survive under changing environmental conditions.
What changing conditions led eurpeans to explore unknown lands in the 1400s?
The changing conditions were that: There was a big storm so they could not cross the ocean to get to the unknown lands in the 1400s
Changes milk to cheese beginning with ewhat?
An enzyme is a protein which acts as a catalyst in causing biochemical reaction, such as changing milk to cheese.
What are the ways rates of chemical change can be changed?
Rate of chemical change can be altered by 1. Changing the temperature. 2. Changing the pressure (if gases are involved). 3. Changing the particle size of a solid reactant. 4. Changing the concentration of a dissolved reactant. 5. Adding a suitable catalyst.
How does changing the temperature of solutions affect the amount of voltage that is going to be produced in votaic cell?
Changing the temperature increases the change in energy.
What is the causes of iron changing to rust when it reacts to water?
Water combines with oxygen to form rust. It is not reacting with water, the water serves as a catalyst.
The study of the Earth's atmosphere and its changing conditions is called what?
meteorology
