increasing

B

decreasing

C

remains unchanged

D

initially increases but decreases subsequently.

Text Solution

Verified by Experts

The correct Answer is:
B
`H_(2)-O_(2)` fuel cell
at anode: `2OH^(-)+H_(2)to2H_(2)O+2e^(-)`
At cathode: `2H_(2)O+O_(2)+4e^(-)to4OH^(-)`

During discharge of a lead storage cell the density of sulphuric acid in the cell:

During the discharge of a lead storage battery, the density of sulphuric acid fell from 1.13 to 1.15 g/ ml^(−1) and sulphuric acid of the density of 1.3 g/ ml^(−1) is 40% by mass and that of the density of 1.15 g/ ml^(−1) is 20% by mass. The battery holds 3.5 litre of acid and the volume practically remained constant during the discharge. Calculate the no. of ampere hour for which the battery must have been used. The charging and discharging reactions are: Pb+SO_(4)^(-2)rarrPbSO_(4)+2e^(-) (charging) PbO_(2)+4H^(+)+SO_(4)^(2-)+2erarrPnSO_(4)+2H_(2)O (discharging)

During the discharge of a lead storage battery, the density of sulphuric acid fell from 1.294 g mL^(-1) to 1.139 g mL^(-) . Sulphuric acid of density 1.294 g mL^(-1) is 39% by weight and that of density 1.139 g mL^(-1) is 20% by weight. The battery hold 3.5 litre of acied and discharge. Calculate the no. of ampere hour for which the battery must have been used. The charging and discharging reactions are: Pb+SO_(4)^(2-) rarr PbSO_(4)+2e (charging) PbO_(2)+4H^(+)+SO_(4)^(2-)+2e rarr PbSO_(4)+2H_(2)O (discharging)
