i dont mean that.. im saying k in electrolysis electrons will be given off because of the chemical reactions.. so in the electrolysis options b c d extra energy was flowing in the circuit..and in a . there was only the cells own energy..theek?
but sorry for being such a nut.

increasing collisions -> faster reaction, pressure decreased-> backward reaction favoured
did u noticed?? exothermic reaction tha!!!
yar lead bromide molten tha us me dont u remember container me tha liquid shape me to it conducts electricity,answer graphite tha kyu k us me sirf ek electron hota haeA answer tha least poocha tha bhai mairay
yeah yar we know
acha ab bc chor bhi do is ek mcq ko baqi theory paper discuss kroi WAS sure that finally a person will agree who have good concepts

The lamp MCQ's answer was liquid mercury, since the mercury never discharges at the electrodes it will cause the lamp to light up dimly. Its similar to a past paper MCQ, they just changed the approach.
In p2, titration question we had to take 30cm3 as the volume since that was the amount neutralizing the acid. I think the concentration was 0.083 as beeloooo said.
In the electrolysis of Copper(II) Sulfate the Cu2+ ions are ALWAYS attracted towards the negative electrode no matter what the conditions, since it is lower than hydrogen. Sulfate ions are never discharged.
In the MCQ relating to Aluminium Oxide's electrolysis, the answer was that Aluminium is always formed at the cathode and Carbon Dioxide/Monoxide is always formed at the anode since the oxygen that is deposited corrodes away the carbon electrode by reacting with it.
Silver Nitrate was the answer for the MCQ regarding how to differentiate between HCl and HNO3 since a white precipitate of Silver Chloride will be formed in that case.

Dont worry, your answer is correct. The question had clearly stated in which electrolysis will the lamp glow LEAST brightly. In solid lead bromide it wont even turn on
