OUESTION 5 Figure 1 reoresents an electrochemical polarzation curses of Zinc plate exposed in 1M hycrochlaric acid and in the peeserce of organic inhibiacs at 50C solution. 3) Write the chemical reactions imovod in the corfesian process. (2 marks) b) What is the type of inhibition showed in the graph? (1 mark) c) How was the type of intibition [answered in (bi) suppressed the corrosion of Zn ? (1 mark) d) Calculate the inhbition elliciency of the orgaric inhibitot using the given current density, L- value. (2) marks) e) With the use of an organic inhibitor in HCI medium, explain the change in current density and potertial. 1) Gve one example of an crganic corrosion irhibitor. (2 marks) (1 mark) 9) What are the possibie actions need to be taken towards the above experiment in order to increase an inhibition officiency? Propses any action
