Following techinique is adopted to check suspected drunk drivers. Read the passage and answer the questions at the end of it. When suspected drunk drivers are tested with a Breathalyzer, the alcohol (ethanol) in the exhaled breath is oxidized to ethanoic acid with an acidic solution of potassium dichromate : 3CH_(3)underset("Ethanol")(CH_(2)OH)(aq)+2Cr_(2)O_(7)^(2-)+16H^(+)(aq)rarr underset("Ethanoic acid")(3CH_(3)COOH)(aq)+4Cr^(3+)(aq)+11H_(2)O(l) The Breathalyzer measures the colour change and produces a meter reading calibrated in terms of blood alcohol content. If the standard half-cell potential for reduction of ethanoic acid to ethanol is 0.06 V and that of reduction of Cr_(2)O_(7)^(2-) to Cr^(3+) is 1.33 V , then E_("cell")^(@) of the reaction taking place in alcohol meter is :
