PH Acidic, basic or neutral? 11.3 (1) 2 (a) For the table below, answer (0.01), (iii) and (iv). Solution [H] рон (OH) ) 3.5 x 107 (iv) [3 marks] (b) A 0.5 M ethanoic acid, CH-COOH is 3.5% dissociated when dissolved in water. Calculate the pH of the acid [4 marks) (c) Consider the following reaction between nitrogen dioxide and carbon monoxide. NO2(g) +CO(g) →→ NO(g) + CO2(g) The initial rate of the reaction was measured at different reactants' concentrations as in table below: Experiment 1 2 INO:1 0.15 0.45 015 ICO 0.01 0.01 003 Initial rate M/s 1.26 1.26 11.34 From the data, determine each of the following: (1) The rate law for the reaction. [2 marks] (1) The rate constant, k for the reaction and state the unit of k. [2 marks] (d) Sketch a graph of concentration versus time for the reaction: 2A + B = 3C if is added to a system at equilibrium. Label the axes appropriately. [4 marks) (e) Draw the Lewis structure and name the molecular geometry for Belz. [3 marks] (1) Draw the orbital overlap of the hybridization of CH4 (label all the bonds) (4 marks] (8) In an electrolysis process, Zn was oxidized and Cu(II) was reduced. Draw a complete diagram (with label) to illustrate the electrolysis process. Abo, write half equations at anode and cathode [5 marks] (h) A current of 0.431 A for 700 s is used to electroplate nickel at the cathode of an electrochemical cell containing NiSO4 (aq). Calculate the mass of nickel metal produced. [Atomic mass: Ni - 58.7; Faraday constant - 96500C/mole'] [3 marks)
