C3- Chemical economics

Can be measured by:

-a catalyst

-concentration

-pressure

-increase in temp ( so particles are more likely to collide as they have more energy)

-increase in surface area

All of them increase the number of successful collisions  

Ouestions- how many number of atoms does:

H2O= 2H 1O

Fe2(SO4)2- 2Fe 1S 7O
