Answer : The rate of change of the total pressure of the vessel is, 10.5 torr/min.
Explanation : Given,
=21 torr/min
The balanced chemical reaction is,
The rate of disappearance of =
The rate of disappearance of =
The rate of formation of =
As we know that,
=21 torr/min
So,
And,
Now we have to calculate the rate change.
Rate change = Reactant rate - Product rate
Rate change = (21 + 10.5) - 21 = 10.5 torr/min
Therefore, the rate of change of the total pressure of the vessel is, 10.5 torr/min.
