Option: 1

H_2 + I_2 \rightleftharpoons 2HI \: \: \: \: \: \: \: \: k_c = 57


Option: 2

H_2 + Cl_2 \rightleftharpoons 2HCl\: \: \: \: \: k_c = 4 \times 10 ^{31}


Option: 3

N_2 + O_2 \rightleftharpoons 2NO\: \: \: \: \: k_c = 4.8 \times 10 ^{-31}


Option: 4

As we have learned

Composition of equilibrium mixture if -1000 < Kc < 1000 -

If kc is in the range of  10-3 to 103 appreciable concentration of both reactants and products are present.

- wherein

e.g.\:H_{2}+I_{2}\rightleftharpoons 2HI

K_{c}=57\:at\:700K

 

 When the value of kc is in b/w -1000 and 1000 then the concentration of reactants and product have appreciable value
