Dear Student,

A      +   2B    ↔   2C  +  D    1
1          1
2              0          0                    (Initial)1
1-x     1
2-2x       2x         x                (At equilibrium)But x = 0
1Therefore, at equilibrium, [A] = 1 1-0
1=1[B]=1 2-2(0 1)=1[C]=2(0 1)=0 2[D]=0
1Therefore, K=[C]2]D][A][B]2or, K=(0 2)2(0
1)(1)(1)2= 4×10-3

1.1 mole of A is mixed with 1.2 mole of B and the mixture is kept in a 1L flask till equilibrium A+2B2C+D is reached. At equilibrium 0.1 mole of D is formed. The Kc of reaction is
