The reason behind the absence of + 1 charge over the given metal for a given amount of metal that is deposited when a given amount of current is passed for a certain period of time is to be stated. Concept introduction: The non-spontaneous reaction takes place in an electrolytic cell in which there occurs conversion of electrical energy into chemical energy and this is used for the electrolysis of a metal. The charge generated in the cell is calculated as, Q = I t When electricity is passed through an electrolytic cell, at that time the amount of the substance that is liberated at an electrode is given by, W = Z Q = Z I t The value of Z is given as, Z = Molar mass n × 96 , 485 To determine: The reason behind the absence of + 1 charge over the given metal for a given amount of metal that is deposited when a given amount of current is passed for a certain period of time.

Solution Summary: The author explains that the non-spontaneous reaction takes place in an electrolytic cell in which there occurs conversion of electrical energy into chemical energy and this is used for the electrolysis of a metal.
Definition Definition Study of chemical reactions that result in the production of electrical energy. Electrochemistry focuses particularly on how chemical energy is converted into electrical energy and vice-versa. This energy is used in various kinds of cells, batteries, and appliances. Most electrochemical reactions involve oxidation and reduction.

Interpretation Introduction
Interpretation:
The reason behind the absence of
+1 charge over the given metal for a given amount of metal that is deposited when a given amount of current is passed for a certain period of time is to be stated.
Concept introduction:
The non-spontaneous reaction takes place in an electrolytic cell in which there occurs conversion of electrical energy into chemical energy and this is used for the electrolysis of a metal.
The charge generated in the cell is calculated as,
Q=It
When electricity is passed through an electrolytic cell, at that time the amount of the substance that is liberated at an electrode is given by,
W=ZQ=ZIt
The value of
Z is given as,
Z=Molarmassn×96,485
To determine: The reason behind the absence of
+1 charge over the given metal for a given amount of metal that is deposited when a given amount of current is passed for a certain period of time.
