The equilibrium constant for the total reaction is
Explanation:
We are given:
We are given two intermediate equations:
Equation 1:
The expression of for the above equation is:
.......(1)
Equation 2:
The expression of for the above equation is:
......(2)
Cubing both the sides of equation 2, because we need 3 moles of HI in the main expression if equilibrium constant.
Now, dividing expression 1 by expression 2, we get:
The above expression is the expression for equilibrium constant of the total equation, which is:
Hence, the equilibrium constant for the total reaction is

Step-by-step explanation:
For this case we can model the problem as a cylinder.
The volume of a cylinder is given by:
Where,
Ab: base area
h: cylinder height
The volcano is 46 centimeters tall and has a
volume of 800 cubic centimeters.
Substituting values in the equation we have:
From here, we can clear the area of the base
An equation that can be used to find the area of the circular base is:
