Which properties cause chemical reactions?

A. chemical and physical properties

B. physical properties

C. chemical properties

D. neither chemical nor physical properties

A chemical reaction occurs when two compounds collide in a certain orientation and with a certain amount of force. Because particles are constantly in motion, random collisions do occur, and some of them will be in the proper orientation. So, as long as the right energy is met will occur.

It depends on both chemical and physical properties
