rate of reaction

adzleen91 asks:

can u explain the effect of temperature on the rate of reaction between sodium thiosulphate and sulphuric acid.

etutor answers:
A reaction occurs when particles of two substances collide with sufficient energy to start a reaction. Increasing the temperature speeds up the particles and so they are more likely to collide and more likely to have sufficient energy to react.

An increase in temperature will increase the kinetic energy of the molecules. That means there will be a greater fraction of the total number of molecules with the activation energy or more. So, there will be more succesful collisions and therefore the rate increases.
