Arrange following reaction in decreasing order on its completion.(i)H_

1.	Arrange following reaction in decreasing order on its completion.(i)H_(2(g)) + Br_(2(g)) hArr 2HBr_((g)) "" K_c=2xx10^9(ii)2CH_(4(g)) hArr C_2H_(6(g)) + H_(2(g)) "" K_c=8.5xx10^(-12) (iii)CH_3OH_((g)) + H_(2(g)) hArr CH_(4(g)) + H_2O_((g)) "" K_c=2.6xx10^21
Answer» Solution :(iii) `to` (i) `to` (II) `K_c:2.6xx10^21 GT 2xx10^9 gt 8.5xx10^(-12)` `to` As the `K_c` decrease completion decrease `to` As `K_c` INCREASE REACTION TOWARDS completion.
