I KNOW IT WAS SOLVED EARLIER BUT I WANT TO MAKE SURE IT'S CORRECT. CAN SOMEONE PLEASE SOLVE IT AGAIN.

EXAMPLE 25: a)The gas phase reaction, A+3B2L+2M, occurs in the constant volume batch tank-type reactor at 227C. Reaction rate equation is not known and not necessary. Initial total pressure 10 atm. Molar compositions of gases are A:%40 and B:%60. The change in concentration of A with respect to time; Draw the curve specific rate with respect [B]=f(t), rB=f(t) and B, change in concentration B,rB=f(B). b) Same reaction in same conditions, same initial concentrations occurs connected in series with 100L and 200L CSTR. The inlet feed is PAO=4atm,PBO=6atm and there is no product. The molar inlet flowrate of A is FAO=4 mole /min. Calculate : i) [A0],[B0],0 and FBO in the first reactor inlet ii) [A1],[B1] and 1 at first reactor outlet(2nd inlet) iii)All molar flowrates of the second reactor outlet
