Electrolysis of an nacl solution with a current of 2.00 a for a period of 200 s produced 59.6 ml of cl2 at 650 mm pressure and 27° c. calculate the value of the faraday from these data.

0.00415F

Explanation:

Given parameters:

Current in the solution = 2A

Time = 200s

Volume of chlorine gas = 59.6mL

Pressure = 650mmHg

Temperature = 27° C

Unknown parameter:

The faraday which is the quantity of electricity used = ?

Solution:

The quantity of electricity used in the reaction is derived from the product of the current passed through the solution and time duration. It is expressed in  coulombs.

      Q = I x t

where I is the current

           t is the time

       Q = 2 x 200 = 400coulombs

One faraday is the quantity of electricity produced by one mole of electrons:

      1Faraday = 96500 coulombs

   Therefore 400coulombs gives = 0.00415F

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
