Answer : The total pressure (in atmospheres) in the reaction vessel when equilibrium reached is, 5.02 atm
Explanation :
First we have to calculate the initial pressure of and
and,
The balanced chemical reaction is:
Initial pressure 2.84 2.84 0
At eqm. (2.84-2x) (2.84-x) 2x
The expression of for above reaction follows:
Putting values in expression 1, we get:
x = 0.664
Now we have to calculate the total pressure.
Partial pressure of = (2x) = 2(0.664) = 1.33 atm
Partial pressure of = (2.84-2x) = [2.84-2(0.664)] = 1.51 atm
Partial pressure of = (2.84-x) = [2.84-0.664] = 2.18 atm
Total pressure = Partial pressure of + Partial pressure of + Partial pressure of
Total pressure = 1.33 + 1.51 + 2.18
Total pressure = 5.02 atm
Thus, the total pressure (in atmospheres) in the reaction vessel when equilibrium reached is, 5.02 atm
