Initial chemical reaction A_(2)underset(K_(-1))overset(K_(1))hArr2A, then (d[A])/(dt)…………

Answer»

`k_(1)[A]_(2)-k_(-1)[A]^(2)`
`2k_(1)[A_(2)]-k_(-1)[A]^(2)`
`2k_(1)[A]_(2)-2k_(-1)[A]^(2)`
`k_(1)[A_(2)]+k_(-1)[A]^(2)`

Solution :Rate=`(-d[A_(2)])/(DT)=(1)/(2)(d[A])/(dt)`
Rate =`k_(1)[A_(2)]-k_(-1)[A]^(2)`
`THEREFORE (1)/(2)(d[A])/(dt)=k_(1)[A_(2)]-k_(-1)[A]^(2)`
`therefore (d[A])/(dt)=2k_(1)[A_(2)]-2k_(-1)[A]^(2)`
