Green Chemistry Toolkit

What is the Definition of Green Chemistry?

• The branch of chemistry that deals with inorganic compounds

• The design of chemical products and processes to reduce or eliminate the generation and use of hazardous substances

• The branch of chemistry that deals with carbon compounds (other than simple salts such as carbonates, oxides, and carbides)

• A scientific concept that seeks to improve efficiency with which natural resources are used to meet human needs for chemical products and services

Which one is NOT a principle of Green Chemistry?

What is a Catalyst?

• A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change

• A substance that takes part in and undergoes change during a chemical reaction

• A specie formed from chemical reactions

• A substance that decreases the rate of a chemical reaction and undergoes permanent chemical change
