How to control rates of a chemical reaction- When you increase the pressure the molecules have less space to move this is an issue because that greater density of molecules  increase the number of collisions. When you decrease the pressure the molecules have more space to move around which doesnt cause as many collisions. So, to control the rate of chemical reactions make sure the pressure is lower so there wont be a change or at least very little change.
