Answer : The number of moles of added must be, 0.37 mol
Explanation :
The given chemical reaction is:
Initial mol. 2.99 x 0 0
At eqm. (2.99-1.30) (x-1.30) 1.30 1.30
= 1.69
The expression for equilibrium constant is:
Now put all the given values in this expression, we get:
x = 1.67 mol
The moles of added = (x-1.30) = (1.67-1.30) = 0.37 mol
