Electrolyse can be used to decompose hydrochloric acid HCI, into its elements. explain the process (its supposed to be a six mark question)

A) the enthralling of formation for pure element in its standard state is always positivehope this : )

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water

The velocity would be 2 

Rate law for this reaction israte of the reaction = k[a]²[b].second order in a  means concentration of a in power of two, and  first order in b means concentration of b in power of one.
