Explain the term 'molecularity' and 'order' of a reaction. Give one example from each of first and second order reaction.

Explain the terms molecularity and order of a reaction. Give one example from each of first and second order reactions. A 0.1 M HCN solution contained 0.2 moles of KCN per litre of the solution. What was the hydronium ion concentration of the solution. (K_(a) for HCN = 7.2 xx 10^(-10) )
