how chemical reactions produce energy, how they cause increase in pressure
« on: April 28, 2005, 02:07:55 PM »
I have a few questions help with answers please for homework :)
Thanks in advance,

I know its got to do with temperature to increase pressure and exothermic reactions.

with reference to high and low explosives: how chemical reactions produce energy, how they cause increase in pressure, the ideal features of an explosive.

1. high reaction rate
2. rapid build-up of pressure (reaction produce gas)
3. highly exothermic

energy is produced due to how fast they collide with the particles of the other reactants . a great deal of energy may be required for a specific collision hence the rise in pressure during the process
