Attainment of the equilibrium `A(g)hArr2C(g)+B(g)`gave the following graph . Find the correct option .`(% dissociation=Fration dissoiatedxx100)`
A. At `=5 "sec equilibrium has been reached and" K_(P)=128 ("mol//litre")^(2)`
B. At `t=5 "sec equilibrium has been reached and" % "dissociation of" A "is" 60%`
C. At `t=5 "sec equilibrium has been reached and" % "dissociation of" A "is" 40%`
D. None of these
