Answers 2 Lets begin with some practice questions Remember to attempt each question before reviewing the answer Question 1 Which of the following is NOT a characteristic of an electrolytic cell a Requires an external power source b Converts electrical energy into chemical energy c Spontaneous reaction d Involves oxidation and reduction halfreactions Answer c Spontaneous reaction Electrolytic cells utilize an external power source to drive nonspontaneous redox reactions Question 2 The standard reduction potential for ZnZn is 076 V and for CuCu is 034 V What is the standard cell potential Ecell for a galvanic cell constructed using these two halfcells a 110 V b 110 V c 042 V d 042 V Answer b 110 V Ecell Ereduction cathode Ereduction anode 034 V 076 V 110 V Cu acts as the cathode reduction and Zn as the anode oxidation Question 3 According to the Nernst equation what happens to the cell potential Ecell when the concentration of reactants increases a Ecell increases b Ecell decreases c Ecell remains unchanged d Ecell becomes zero Answer a Ecell increases The Nernst equation shows that increasing reactant concentration increases the reaction quotient Q leading to a higher Ecell value Question 4 Which of the following applications does NOT directly utilize electrochemistry principles a Battery technology b Corrosion protection c Combustion engine operation d Electroplating 3 Answer c Combustion engine operation Combustion engines rely on chemical combustion not electrochemical processes Question 5 What is the primary role of a salt bridge in an electrochemical cell a To increase the cell potential b To maintain electrical neutrality c To speed up the reaction rate d To prevent mixing of solutions Answer b To maintain electrical neutrality
