Explanation The given equation is as follows, HNO 2 (aq) + NH 3 (aq) ⇌ NH 4 + (aq) + NO 2 − (aq) Now, write the expression for equilibrium constant from the above reaction. K = [ NH 4 + ] [ NO 2 − ] [ HNO 2 ] [ NH 3 ] The NH 4 + ion formation reaction equation is the combination of the following two equations and it can be written as, HNO 2 (aq) + H 2 O (l) ⇌ H 3 O + (aq) + NO 2 − (aq) NH 3 (aq) + H 2 O (l) ⇌ NH 4 + (aq) + OH - (aq) The equations represents the weak acid dissociation and weak base dissociation. Now, write the expressions for both acid and base dissociation constants for the above two equation as below. K a = [ H 3 O + ] [ NO 2 − ] [ HNO 2 ] K b = [ NH 4 + ] [ OH - ] [ NH 3 ] At 298K, K a of HNO 2 is 4 .3×10 -4 K b of NH 3 is 1 .8×10 -5 . Now, substitute these values in the above expression and it becomes, 4 .3×10 -4 = [ H 3 O + ] [ NO 2 − ] [ HNO 2 ] 1 .8×10 -5 = [ NH 4 + ] [ OH - ] [ NH 3 ] Now, multiply the above equations, 4 .3×10 -4 ×1
