1.	An electrolytic cell is constructed for preparing hudrogen. For an averge current of `1` amper in the circuit , the time required to produce `450 mL` of hydrogen at `NTP` is appr.A. ` 30` minB. `1` hourC. ` 2` hoursD. ` 5` hours
Answer» Correct Answer - B ` 22, ml H_2 at STP + 1 mol H_2` `:. 450 mL H_2 at STP= ( 450 mL)/(22. 400mL) xx 1 "mole" [email protected]` `= 0.02` mol Electrode reaction : ` 2H^+ +2E^(-_ rarrH_2` `2 F 1 mli` So, the liberation of `0.02` mole of `H_2` required `=2 xx 96, 500 xx 0.02 C = 3860 C` Time required to produce `0.2` mole `H_2 = Q/I = ( 3. 860)/(1 A) = 1.07 ~~1` hour .
