Expert Solution
Step 1

For the equilibrium Reaction -

2NOCl <-----> 2NO + Cl2

The , Equilibrium constant can be written as -

Kc = concentration of Products/concentration of Reactants

Kc = [NO]2[Cl2]/[NOCl]2

Here,

Kc = 1.6×10-5

[NO] =  moles of NO = ?

[Cl2] = moles of Cl2 = 0.981 mole

[NOCl] = moles of NOCl = 1 mole
