explain why a high temperature is needed to melt potassium iodide??
oh and can anyone explain why changing the pressure does not affect the yield oh hydrogen at equilibrium???
for the first one i think is because it is bonded ionically so a high temp is needed to break the electrostic bonds :)
okayy, thank you very much!! :)
No problem :) im not sure about the second one sorry
don't worry, thanks for your help though
This should be in the chemistry section...
The production of Hydrogen is to do with le chat. principle. Increasing pressure of a gaseous system is similar to that of increasing concentrations of aqueous systems; the equalibria will move to oppose the disturbance. if by increasing the pressure there are more moles/molecules on the reactants side than there is on the products side then the equalibrium will favor the forward reaction. If there are more moles of gas produced on the reactants side then it will favor the reverse reaction and less products will be produced as the rate of both reactions has lowered.
thanks so much!!!
