Answer: The value of for the given reaction is .
Explanation:
The ratio of concentration of products and reactants raised to the power of their concentration is called equilibrium constant.
It is denoted by the symbol .
For example,
The expression for of this reaction is as follows.
So, by putting the respective concentrations of the species involved in the reaction it is possible to determine the value of for the given reaction.
Thus, we can conclude that the value of for the given reaction is .
Answer: 42 hours
Explanation:
Moles of electron = 1 mole
According to mole concept:
1 mole of an atom contains number of particles.
We know that:
Charge on 1 electron =
Charge on 1 mole of electrons =
According to stoichiometry:
1 mole of electrons deposit = 23 g of sodium
i.e 96500 C of electricity deposit = 23 g of sodium
Thus 23 g of sodium is deposited by = 96500 C of electricity
of sodium is deposited by = C of electricity
To calculate the time required, we use the equation:
where,
I = current passed =
q = total charge =
t = time in secods = ?
Putting values in above equation, we get:
Thus 42 hours are required.
