Concept Introduction:
Le Chatelier’s principle states that whenever there is the effect of change in the conditions on an equilibrium reaction, the equilibrium will shifts in the direction so as to neutralize the effect.
(b)
Interpretation:
The time period for which the battery can operate has to be calculated.

- An aqueous solution of an unknown salt of vanadium is electrolyzed by a current of 2.50 amps for 1.90 hours. The electroplating is carried out with an efficiency of 95.0%, resulting in a deposit of 2.850 g of vanadium. a How many faradays are required to deposit the vanadium? b What is the charge on the vanadium ions (based on your calculations)?arrow_forwardAn aqueous solution of an unknown salt of gold is electrolyzed by a current of 2.75 amps for 3.39 hours. The electroplating is carried out with an efficiency of 93.0%, resulting in a deposit of 21.221 g of gold. a How many faradays are required to deposit the gold? b What is the charge on the gold ions (based on your calculations)?arrow_forwardIn the electrolysis of a solution containing Ni2+(aq), metallic Ni(s) deposits on the cathode. Using a current of 0.150 A for 12.2 minutes, what mass of nickel will form?arrow_forward
- What volume of F2 gas, at 25C and 1.00 atm, is produced when molten KF is electrolyzed by a current of 10.0 A for 2.00 h? What mass of potassium metal is produced? At which electrode does each reaction occur?arrow_forwarda Calculate the equilibrium constant for the following reaction at 25C. Sn(s)+Pb2+(aq)Sn2+(aq)+Pb(s) The standard cell potential of the corresponding voltaic cell is 0.010 V. b If an excess of tin metal is added to 1.0 M Pb2+, what is the concentration of Pb2+ at equilibrium?arrow_forwardThe black silver sulfide discoloration of silverware can be removed by heating the silver article in a sodium carbonate solution in an aluminum pan. The reaction is 3Ag2S(s)+2Al(s)6Ag(s)+3S2(aq)+2Al3+(aq) a. Using data in Appendix 4, calculate G, K, and for the above reaction at 25C. [For Al3+(aq), Gf = 480. kJ/mol.] b.
