(i) The half-life period (t ½) for decay of radioactive ¹⁴C is 5730 years. An ancient piece of wood has only 80% of the ¹⁴C found in a living tree. Calculate the age of the piece of wood.
(ii) The rate of most of the reactions becomes double when the temperature is raised from 298K to 308K. Calculate the activation energy. (R = 8ˑ314 J K^-1 mol^-1 )
