A first-order reaction is 50% completed in 40 minutes at 300 K and in 20 minutes at 320 K. Calculate the activation energy of the reaction.
(Given: log 2 = 0.3010, log 4 = 0.6021, R = 8.314 JK–1 mol–1)
What happens when
A freshly prepared precipitate of Fe(OH)3 is shaken with a small amount of FeCl3 solution?
What happens when
An emulsion is centrifuged?
When an emulsion is centrifuged, demulsification takes place, i.e. the emulsion is broken into constituent liquids.
