3. A gaseous chemical reaction below is taking place in a batch reactor, the volumetric flow rate at the end of the reaction was n-times of its initial value. Final conversion of A was XA. Temperature, pressure, and volume at initial stage were T0,P0 and V0. During the reaction, you can denote temperature, pressure and volume as T,P and V, respectively. Initially, compositions of A, B and inert were 20%,20% and 60%, respectively. Reaction : A(g)+B(g)R(g)+S(g) (a) Derive the relationship between V at the end of reaction and V0 (b) Express CA in terms of stoichiometric coefficients and conversion of A
