Write the expression for the equilibrium constant `K_(c )` for each of the following reactions:
a. `2NOCl(g) hArr 2NO(g)+Cl_(2)(g)`
b. `2Cu(NO_(3))_(2)(s) hArr 2CuO(s)+4NO_(2)(g)+O_(2)(g)`
c. `CH_(3)COOC_(2)H_(5)(aq)+H_(2)O(1) hArr CH_(3)COOH(aq)+C_(2)H_(5)OH(aq)`
d. `Fe^(3+)(aq)+3OH^(Θ)(aq) hArr Fe(OH)_(3)(s)`
e. `I_(2)(s)+5F_(2) hArr 2IF_(5)`

Explanation

a. `K_(c )=([NO(g)]^(2)[Cl_(2)(g)])/([NOCl(g)]^(2))`
b. `K_(c )=([CuO(s)]^(2)[NO_(2)(g)]^(4)[O_(2)(g)])/([Cu(NO_(3))_(2)(s)]^(2))`
`=[NO_(2)(g)]^(4)[O_(2)(g)]`
c. `K_(c )=([CH_(3)COOH(aq)][C_(2)H_(5)OH(aq)])/([CH_(3)COOC_(2)H_(5)(aq)][H_(2)O(l)])`
d. `K_(c )=([Fe(OH)_(3)(s)])/([Fe^(3+)(aq)][OH^(Θ)(aq)]^(3))=1/([Fe^(3+)(aq)][OH^(Θ)(aq)]^(3))`
e. `K_(c )=([IF_(5)(l)]^(2))/([I_(2)(s)][F_(2)(g)]^(5))=([IF_(5)(l)]^(2))/([F_(2)(g)]^(5))`
