Answer: Option (B) is the correct answer.
Explanation:
Expression for the given decomposition reaction is as follows.
Let us assume that x concentration of is present at the initial stage. Therefore, according to the ICE table,
Initial : x 0
Change : - 0.1
Equilibrium : (x - 0.1) 0.2
Now, expression for of this reaction is as follows.
Putting the given values into the above formula as follows.
x = 0.12
This means that = x = 0.12 atm.
Thus, we can conclude that the initial pressure in the container prior to decomposition is 0.12 atm.
Answer:
,
Explanation:
The change in energy is given by the change in gravitational potential energy:
The average rate of change in terms of time is approximately this:
