Given information

The amount of electricity used per month is.

 

Step-by-step explanation

Step 1.
A hydrogen-oxygen fuel cell generator is used to produce electricity for a house.
The half cell reaction at cathode is,
 ……(1)
The half cell reaction at anode is,
 ……(2)
The overall cell reaction for the given fuel cell is obtained by adding equation (1) and equation (2).
 ……(3)
The standard cell potential is calculated by the formula,
 
Where,
  •   is the cell potential of equation (1).
  • is the cell potential of equation (2).
Substitute the value of and in the above equation.
 
The maximum amount of work that can be done is calculated by the formula,
 
Where,
 
The value of for the reaction is 4.
Substitute the value of, and in the above equation.
