Rate of a chemical reaction 2A (g) to B(g) is defined as : 'r_B'=1/V(dn_B)/(dt) Where n_B=number of moles of B formed and C_B =Concentration of B then which of the following relation correct .

Answer»

`r_B=(dC_B)/(dt)+(C_B)/V(DV)/(dt)` (If volume V is not CONSTANT )
`r_B=(dC_B)/(dt)`(If volume V is constant)
`r_B=(dC_B)/(dt)-(C_B)/V(dV)/(dt)` (If volume V is not constant )
`r_B=-(dC_B)/(dt)+(C_B)/V(dV)/(dt)` (If volume V is not constant )

SOLUTION :`r_B=(dC_B)/(dt)=1/V(dn_B)/(dt)=1/V(d(C_BV))/(dt)=V/V(dC_B)/(dt)+C_B/V(DV)/(dt)=(dC_B)/(dt)+C_B/V(dV)/(dt)`
