In a reversible reaction `Aunderset(K_2)overset(K_1)hArrB` the initial concentration of A and B are a and b in moles per litre and the equilibrium concentrations are (a-x) and (b+x) respectively, Express x in terms of `K_1, K_2, a and b`.

A

`(k_(1)a-k_(2)b)/(k_(1)+k_(2))`

B

`(k_(1)a-k_(2)b)/(k_(1)-k_(2))`

C

`(k_(1)a-k_(2)b)/(k_(1)k_(2))`

D

`(k_(1)a+k_(2)b)/(k_(1)+k_(2))`
