Write the expression for the equilibrium constant, K_c for each of the

1.	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) (c )CH_3COOC_2H_5 hArr CH_3COOH(aq)+C_2H_5OH(aq) (d)Fe^(3+)(aq) +3OH^(-) (aq) hArr Fe(OH)_3(s) (e) I_2(s) + 5F_2(s) hArr 2IF_5(g)
Answer» Solution :(a)`2NOCl(g) hArr 2NO(g)+Cl_2(g)` `K_c=([NO]^2 [Cl_2])/([NOCl]^2)` (b)`2Cu(NO_3)_2(s) hArr 2CuO(s) +4NO_2(g) +O_2(g)` `K_c=[NO_2]^4[O_2]` (c ) `CH_3COOC_2H_5(aq)+H_2O(L) hArr CH_3COOH(aq)+C_2H_5OH(aq)` `K_c=([CH_3COOH][C_2H_5OH])/([CH_3COOC_2H_5])` (d)`FE^(3+)(aq)+3OH^(-)(aq) hArr Fe(OH)_3(s)` `K_c=1/([Fe^(3+)][OH^-]^3)` (e) `I_2(s) + 5F_2(g) hArr 2IF_5(g)` `K_c=([IF_5]^2)/([F_2]^5)`
