FOR Chemistry PAPER 33!!!!!!!!!!
hydrated ammonim salt titrated with KMnO4
usual salt analysis
one thermal question
We have to titrate ammonium nitrate with KMn04 or would we need to oxidize potassium iodide in the
presence of ammonium nitrate and then titrate the resulting solution with sodium thiosulphate? :|
see question no.1 in june2008-31
a similar question is expected!

The energy of the collision
Activation Energy
Even if the species are orientated properly, you still won't get a reaction unless the particles collide with a certain minimum energy called the activation energy of the reaction.
Activation energy is the minimum energy required before a reaction can occur. You can show this on an energy profile for the reaction. For a simple over-all exothermic reaction, the energy profile looks like this:

The Maxwell-Boltzmann Distribution and activation energy
Remember that for a reaction to happen, particles must collide with energies equal to or greater than the activation energy for the reaction. We can mark the activation energy on the Maxwell-Boltzmann distribution:
Notice that the large majority of the particles don't have enough energy to react when they collide. To enable them to react we either have to change the shape of the curve, or move the activation energy further to the left. This is described on other pages.
