19821 The mass of a substance liberated when a charge '\(q\)' flows through an electrolyte is proportional to

1 \(q\)
2 \(1/q\)
3 \({q^2}\)
4 \(1/{q^2}\)
ELECTROCHEMISTRY

19822 A steady current of \(5\, amps\) is maintained for \(45\, mins\). During this time it deposits \(4.572\, gm\) of zinc at the cathode of a voltameter. \(E.C.E.\) of zinc is

1 \(3.387 \times {10^{ - 4}}gm/C\)
2 \(3.387 \times {10^{ - 4}}C/gm\)
3 \(3.384 \times {10^{ - 3}}gm/C\)
4 \(3.394 \times {10^{ - 3}}C/gm\)
ELECTROCHEMISTRY

19823 The relation between faraday constant \(F\), electron charge \(e\) and avogadro number \(N\) is

1 \(F = N/e\)
2 \(F = Ne\)
3 \(N = {F^2}\)
4 \(F = {N^2}e\)
ELECTROCHEMISTRY

19824 The electrochemical equivalent of magnesium is \(0.126\,mg/C\). A current of \(5\, A\) is passed in a suitable solution for \(1\) hour. The mass of magnesium deposited will be ........... \(\mathrm{gm}\)

1 \(0.0378\)
2 \(0.227\)
